Hybrid Email Marketing software for small and medium businesses.
How to Choose the Best Email Marketing Software
Email marketing software helps businesses build subscriber lists, create campaigns, automate customer communication, segment audiences, measure engagement, and maintain ongoing relationships with leads and customers.
The best platform depends on what email is expected to do inside your business.
A newsletter creator may mainly need an easy editor, signup forms, and affordable subscriber pricing. An ecommerce store may care more about abandoned carts, product recommendations, customer segments, and purchase-triggered automation. A B2B company may need lead nurturing and CRM integration. A larger sender may place deliverability controls, permissions, reporting, and sending infrastructure above design features.
Start by identifying your main email workflow, expected list size, monthly sending volume, and required integrations.
Then compare products based on the features you will actually use.
Best Email Marketing Software by Use Case
| Email Marketing Software | Best For | Why Consider It |
|---|---|---|
| Mailchimp | Small businesses wanting a broad marketing platform | Combines email campaigns, audience management, automation, segmentation, reporting, forms, and integrations |
| MailerLite | Beginners, creators, and small businesses | Focuses on accessible newsletter creation, automation, signup forms, landing pages, and straightforward campaign workflows |
| Klaviyo | Ecommerce and B2C brands | Strong fit for customer-data-driven lifecycle marketing, segmentation, ecommerce automation, and multi-channel customer journeys |
| Omnisend | Ecommerce teams combining email and SMS | Designed around ecommerce campaigns and automated customer lifecycle messaging |
| ActiveCampaign | Businesses needing deeper automation | Suitable for teams that place workflow automation, customer journeys, and behavioral messaging at the center of email marketing |
| GetResponse | Businesses wanting email plus broader marketing tools | Combines email campaigns with automation and other digital marketing capabilities |
| AWeber | Small businesses and newsletter marketers | Long-established platform focused on email campaigns, subscriber management, automation, and integrations |
| Sender.net | Cost-conscious businesses and ecommerce teams | Email marketing platform with automation, segmentation, integrations, and ecommerce-oriented use cases |
| Campaigner | Businesses running more structured email campaigns | Designed around email campaign creation, automation, personalization, and list management |
These are use-case recommendations rather than a single universal ranking.
The best software for a Shopify store may be unnecessarily complex for a consultant sending one newsletter each week. Likewise, a simple newsletter tool may not provide enough automation for a business managing thousands of customer journeys.
What Is Email Marketing Software?
Email marketing software helps businesses communicate with groups of subscribers through email.
Instead of sending messages manually from a normal inbox, email marketing platforms provide tools for managing mailing lists, designing campaigns, automating messages, segmenting audiences, and measuring performance.
Common capabilities include:
- email campaign creation
- newsletter design
- subscriber management
- signup forms
- segmentation
- personalization
- marketing automation
- drip campaigns
- A/B testing
- templates
- analytics
- landing pages
- transactional emails
- ecommerce integrations
- CRM integrations
- API access
Some products focus mainly on newsletters.
Others have developed into broader customer-engagement platforms that combine email with SMS, mobile messaging, CRM data, customer profiles, ecommerce events, and automated lifecycle campaigns.
Understanding which type of platform you need can prevent you from paying for functionality your team never uses.
Types of Email Marketing Software
Newsletter Software
Newsletter software is designed for businesses and creators that regularly publish email content to a subscriber audience.
Typical requirements include:
- drag-and-drop email editing
- reusable templates
- signup forms
- subscriber lists
- scheduling
- audience segments
- analytics
- unsubscribe management
Creators, publishers, consultants, communities, and small businesses often do not need complicated automation when they first begin.
Ease of use can matter more than advanced functionality.
Email Automation Software
Email automation allows messages to be sent automatically when a subscriber meets a particular condition or performs an action.
A workflow may begin when someone:
- joins a mailing list
- downloads a resource
- purchases a product
- abandons a cart
- clicks a particular link
- reaches a customer milestone
- stops engaging
- submits a form
The software can then send one message or a sequence of messages without someone manually launching each campaign.
Common automated workflows include:
Welcome series: Introduce new subscribers to the brand.
Lead nurturing: Educate prospects over several messages.
Abandoned cart: Remind shoppers about products they left behind.
Post-purchase: Send onboarding, product education, or follow-up content.
Win-back campaigns: Re-engage customers who have become inactive.
Renewal reminders: Notify customers before subscriptions or services expire.
Automation becomes more useful as customer journeys become more complex.
Ecommerce Email Marketing Software
Ecommerce businesses have requirements that go beyond ordinary newsletters.
Their email platform may need access to:
- products
- orders
- customer purchase history
- shopping carts
- browsing behavior
- customer value
- discounts
- inventory events
This information can support automated campaigns such as:
- abandoned-cart reminders
- welcome sequences
- browse abandonment
- product recommendations
- post-purchase education
- back-in-stock messages
- review requests
- replenishment reminders
- VIP campaigns
- win-back sequences
Klaviyo and Omnisend are particularly associated with ecommerce lifecycle marketing, while platforms such as Mailchimp and MailerLite also support ecommerce integrations and automated campaigns.
For an online store, the quality of the ecommerce integration is often more important than the number of email templates included.
Email Marketing Deliverability
Deliverability is one of the most important factors when comparing email marketing software.
Sending an email successfully does not automatically mean it reached the recipient’s inbox.
Messages may be delivered to the inbox, placed in spam, rejected, delayed, or filtered by the recipient’s email provider.
Several factors can affect deliverability, including:
- sender authentication
- domain reputation
- sending reputation
- list quality
- spam complaints
- bounced addresses
- subscriber engagement
- sending behavior
- email content
- opt-out handling
The email platform provides infrastructure and tools, but the sender also has responsibility for maintaining healthy sending practices.
SPF, DKIM, and DMARC
Businesses sending marketing email from their own domains should understand email authentication.
Common authentication mechanisms include:
SPF: Helps identify which servers are permitted to send email for a domain.
DKIM: Adds a cryptographic signature that helps receiving systems verify that the message was authorized by the sending domain.
DMARC: Builds on SPF and DKIM and gives domain owners greater control over how authentication failures are handled and reported.
Businesses sending significant volumes of email should treat domain authentication as a core setup task rather than an optional technical feature.
List Quality Matters
A large mailing list is not automatically a valuable mailing list.
Businesses should avoid purchasing lists or repeatedly sending campaigns to people who did not ask to receive them.
Healthy email programs usually focus on:
- permission-based subscriber acquisition
- clear signup expectations
- easy unsubscribe
- removing invalid addresses
- monitoring engagement
- managing complaints
- segmenting audiences
Software can provide the tools, but deliverability ultimately depends on how those tools are used.
Email Marketing Automation Features to Compare
Automation builders can vary substantially between products.
Before choosing a platform, examine how workflows actually work.
Automation Triggers
Useful triggers may include:
- subscriber added
- form submitted
- email opened
- link clicked
- product purchased
- cart abandoned
- customer anniversary
- date reached
- customer segment entered
- custom event received
Ecommerce platforms may provide additional triggers based on purchase and browsing activity.
Conditional Logic
More advanced automation allows different subscribers to take different paths.
For example:
Customer purchased → Send onboarding
Customer did not purchase → Continue nurture sequence
This creates more relevant customer journeys than sending the same sequence to everyone.
Delays and Timing
Automation should let marketers control how much time passes between messages.
Timing may depend on:
- minutes
- hours
- days
- specific dates
- subscriber timezone
- customer action
Segmentation
Segmentation allows businesses to send different messages to different groups.
Segments may be based on:
- location
- interests
- signup source
- purchase history
- engagement
- lifecycle stage
- customer value
- website behavior
Better segmentation generally creates a more relevant subscriber experience than sending every campaign to the entire database.
Email Marketing Features to Compare
Email Editor
The editor should make it easy to create emails that work across desktop and mobile devices.
Common editing options include:
- drag-and-drop blocks
- text
- images
- buttons
- columns
- product blocks
- saved sections
- HTML editing
Teams with strict brand requirements should also check how much control they have over typography, spacing, reusable styles, and templates.
Templates
Templates can speed up campaign creation.
Look for templates relevant to the messages your team actually sends rather than choosing a platform because it advertises the largest template library.
Signup Forms
Forms help convert website visitors into subscribers.
Common form types include:
- embedded forms
- popups
- landing pages
- signup pages
Ecommerce businesses may also need behavior-based forms and integrations with their store.
Segmentation
Segmentation becomes increasingly important as a subscriber list grows.
A small newsletter may initially send similar content to everyone.
A larger marketing program may separate:
- prospects
- customers
- VIP customers
- inactive subscribers
- product interests
- regions
- lifecycle stages
Personalization
Basic personalization may insert a subscriber’s name.
More advanced platforms can personalize content using customer attributes, purchase behavior, interests, location, or other data.
A/B Testing
A/B testing allows marketers to compare different campaign versions.
Common tests include:
- subject lines
- sender names
- email content
- calls to action
- send times
The value of testing increases when the audience is large enough to produce meaningful results.
Analytics
Useful email marketing metrics may include:
- delivered emails
- opens
- clicks
- click-through rate
- bounces
- unsubscribes
- spam complaints
- conversions
- revenue
Ecommerce platforms may connect campaign activity directly with orders and sales.
Do not evaluate campaign success using open rate alone. Privacy features and email-client behavior can make opens less reliable than clicks, conversions, replies, or revenue for many use cases.
Email Marketing Software Pricing
Email marketing pricing can become complicated because vendors do not all charge in the same way.
Pricing may depend on:
- number of contacts
- number of active subscribers
- emails sent per month
- users
- automation features
- advanced reporting
- SMS usage
- transactional email
- customer data features
- support level
Two platforms with a similar advertised starting price may become very different in cost when the list reaches 10,000 or 100,000 subscribers.
Contact-Based Pricing
Many email tools increase the subscription price as the number of stored or active contacts grows.
Before migrating a large list, understand exactly which contacts count toward billing.
Send-Based Pricing
Some platforms focus more heavily on the number of emails sent.
This model can be attractive for businesses with a large database that emails subscribers relatively infrequently.
Feature-Based Pricing
Advanced automation, reporting, permissions, testing, or customer-data functionality may only be available on higher plans.
The cheapest plan may therefore not represent the price of the features you actually require.
Calculate the Real Cost
Before selecting email marketing software, estimate:
Expected subscribers + monthly email volume + required automation + team users + ecommerce or CRM integrations + transactional email + additional channels
Then compare providers using the same expected workload.
Free Email Marketing Software
Several email marketing platforms provide free plans or trials.
Free plans can be useful for:
- new newsletters
- startups
- creators
- small local businesses
- testing a platform before migration
However, free tiers may limit:
- subscribers
- monthly sends
- automation
- templates
- branding removal
- reporting
- support
- users
The best free platform is the one with an upgrade path that still makes sense when the email list grows.
Email Marketing Software for Small Businesses
Small businesses should usually prioritize simplicity, affordability, and enough automation to remove repetitive work.
Useful features include:
- easy campaign creation
- subscriber management
- signup forms
- templates
- basic segmentation
- automation
- analytics
- integrations
Mailchimp, MailerLite, AWeber, GetResponse, Sender.net, and similar platforms may all be worth comparing depending on the size and complexity of the business.
Avoid paying for advanced functionality simply because you may need it someday.
Email Marketing Software for Ecommerce
Ecommerce teams should evaluate email platforms through the customer lifecycle rather than only campaign creation.
A strong ecommerce setup may support:
Visitor → Subscriber → First Purchase → Repeat Purchase → VIP Customer
Email can support every stage.
Important capabilities include:
- Shopify or WooCommerce integration
- customer synchronization
- abandoned-cart automation
- product recommendations
- customer segmentation
- purchase-triggered workflows
- revenue reporting
- customer lifecycle automation
Klaviyo and Omnisend are especially relevant to ecommerce-focused comparisons, while Mailchimp, MailerLite, and other platforms also provide ecommerce functionality.
Email Marketing Software for Creators and Newsletters
Creators often need a simpler workflow:
Capture subscriber → Publish newsletter → Build audience → Monetize
Useful features include:
- signup pages
- forms
- email editor
- scheduled newsletters
- automation
- subscriber tagging
- landing pages
- paid subscriptions or digital product features
Avoid selecting an enterprise marketing platform if most of its functionality has little connection with the newsletter business model.
Email Marketing for B2B Companies
B2B email marketing often centers on longer sales cycles.
Relevant workflows include:
- lead nurturing
- webinar follow-up
- content downloads
- demo requests
- account engagement
- sales handoff
- re-engagement
CRM integration becomes particularly important.
Marketing teams should be able to understand when a contact becomes sales-ready, while sales teams should have enough context about previous marketing activity.
Email Marketing Software vs Marketing Automation Software
Email marketing and marketing automation overlap, but they are not identical.
Email marketing software primarily focuses on building lists, creating campaigns, sending messages, automating email sequences, and analyzing results.
Marketing automation software may coordinate a broader customer journey across multiple channels and systems.
It may include:
- lead scoring
- CRM activity
- forms
- website behavior
- SMS
- customer segmentation
- workflow automation
A small business may be able to handle most requirements inside an email marketing platform.
A business managing complicated lead or customer journeys may eventually need broader marketing automation.
Email Marketing vs SMS Marketing
Email is suited to longer communication, newsletters, product education, visual content, and campaigns where readers may need more information.
SMS is more appropriate for shorter and more time-sensitive messages.
Examples include:
- reminders
- urgent notifications
- short promotions
- appointment alerts
- time-sensitive offers
Many businesses use both.
If SMS is important to your marketing strategy, compare the SMS Marketing Software category on HowToBuySaaS as well.
Email Marketing vs WhatsApp Marketing
Email and WhatsApp serve different customer communication patterns.
Email works well for newsletters, longer educational content, lifecycle sequences, and scheduled marketing.
WhatsApp can support faster conversations, chatbots, notifications, sales interactions, and customer support.
Businesses operating across several communication channels should decide whether they want separate specialist tools or an omnichannel platform.
Explore the WhatsApp Marketing Software category if WhatsApp is an important part of your customer engagement strategy.
Email Marketing Integrations
Email marketing becomes more useful when it connects with other customer systems.
Ecommerce Integrations
Online stores should check for native connections with:
- Shopify
- WooCommerce
- BigCommerce
- other ecommerce systems
A native integration can allow customer and purchase information to trigger automated campaigns.
CRM Integrations
CRM integration is useful for B2B and sales-led organizations.
It can help connect:
Lead acquisition → Marketing nurture → Sales opportunity → Customer
without requiring teams to manually move data between systems.
Website Integrations
Common website connections include:
- WordPress
- forms
- landing pages
- website builders
Automation Platforms
Integrations with workflow tools can help connect email software with applications that lack a direct integration.
API and Webhooks
Technical teams may need API access for:
- subscriber creation
- custom events
- transactional workflows
- user synchronization
- internal applications
Check developer documentation before buying if the API is important to your implementation.

Campaign Creation
We consider how easily marketers can create, preview, schedule, and manage campaigns.
Automation
We look at available triggers, conditions, workflow controls, personalization, and how easy automation is to maintain.

The platform should provide practical tools for lists, segments, tags, subscriber data, opt-outs, and audience organization.
Deliverability Tools
We consider whether the platform helps users configure authentication, understand delivery problems, manage bounces, and maintain healthy sending practices.
Integrations
We evaluate connections with ecommerce platforms, CRMs, websites, analytics software, and other marketing systems.

Limits may apply to subscriber counts, monthly sends, automation, branding, reporting, or support.
Which email marketing software is best for small businesses?

Klaviyo and Omnisend are strongly focused on ecommerce and customer lifecycle marketing.
Other platforms such as Mailchimp and MailerLite also provide ecommerce integrations and automation.
The best choice depends on your store platform, customer data, automation needs, and expected messaging volume.
What is email marketing automation?
Email marketing automation uses rules or customer actions to trigger messages automatically.
Common examples include welcome sequences, abandoned-cart reminders, lead nurturing, post-purchase emails, and re-engagement campaigns.
What is email deliverability?
Email deliverability refers to whether a message successfully reaches the intended inbox rather than being rejected, filtered, or placed in spam.
Deliverability can be affected by authentication, reputation, list quality, engagement, complaints, and sending behavior.
Do I need SPF, DKIM, and DMARC for email marketing?
Businesses sending marketing email from their own domains should configure appropriate email authentication.
SPF, DKIM, and DMARC help receiving mail systems verify legitimate senders and protect domains against certain forms of spoofing and abuse.
Is email marketing software the same as CRM software?
No.
Email marketing software focuses primarily on subscriber communication and campaigns.
CRM software primarily manages leads, contacts, customer relationships, sales opportunities, and customer history.
Many businesses integrate both systems.
Is email marketing software the same as marketing automation?
Not necessarily.
Email automation can exist inside a normal email platform.
Broader marketing automation may manage several channels, lead scoring, CRM activity, customer data, and more complex workflows.
Can email marketing software integrate with Shopify?
Many platforms offer Shopify integrations.
The depth of the integration varies, so ecommerce businesses should check whether customer, order, cart, product, and revenue data can be used inside campaigns and automation.
How much does email marketing software cost?
Pricing depends on the provider and may be based on subscribers, contacts, email sends, users, features, or a combination of these.
Always calculate pricing at your expected future list size rather than only comparing entry-level plans.
Can email marketing software improve deliverability?
A good platform can provide sending infrastructure and tools that support healthy email practices, but no provider can guarantee inbox placement.
Subscriber consent, sender reputation, authentication, list quality, engagement, and campaign practices also affect results.
