What Should an Email Marketing Automation Tool Do?
A useful email marketing automation platform should help your business:
- Capture and organize subscribers
- Create signup forms and landing pages
- Send welcome email sequences
- Segment contacts by behaviour or interests
- Recover abandoned shopping carts
- Promote new products and seasonal offers
- Deliver lead magnets automatically
- Follow up with leads and customers
- Test different subject lines and messages
- Track clicks, conversions and campaign performance
- Keep communication consistent across the customer journey
Start with one valuable automation before building a complicated workflow. A simple welcome series or abandoned-cart sequence can often deliver more value than an unfinished automation with dozens of branches.
1. Omnisend
Omnisend is built for ecommerce and supports email, SMS, and automation workflows. It gives stores Klaviyo-comparable lifecycle messaging at up to 35% lower cost, with a free five-day migration included.
The platform allows ecommerce businesses to combine email, SMS, and push notifications within the same automation workflow. Stores can create campaigns for welcome messages, abandoned carts, product recommendations, order follow-ups, customer reactivation, and seasonal promotions.
Omnisend also provides AI-supported tools for writing campaign content, identifying customer segments, and improving the timing and relevance of marketing messages.
According to Omnisend’s current comparison, eligible businesses may save up to 35% compared with Klaviyo. Actual savings depend on factors such as contact-list size, plan level, billing frequency, region, and selected features.
Best for:
- Ecommerce campaigns
- Email plus SMS
- Abandoned-cart flows
- Klaviyo-comparable automation
- Product recommendations

Why it stands out: Omnisend combines ecommerce-focused automation with multiple communication channels, helping stores manage more of their customer journey without connecting several separate marketing platforms.
Recommended for: Shopify, WooCommerce and other ecommerce businesses looking for an alternative to Klaviyo or a more specialized solution than a general newsletter platform.
2. MailerLite
MailerLite is one of the easiest email marketing automation tools for beginners. It offers a clean interface, visual automation features, signup forms, landing pages, email campaigns, and audience-management tools.
It is suitable for small businesses that want to build straightforward workflows without spending weeks learning a complex marketing platform.
Best for:
- Welcome email sequences

3. Mailchimp
Mailchimp is a widely recognized email marketing platform with campaign templates, audience management, signup forms, reporting, and customer-journey features.
It works well for small businesses that want a familiar platform for newsletters and basic automation. However, businesses should compare plan limits carefully as their contact lists and automation requirements grow.
Best for:
- Newsletter campaigns
- Promotional emails
- Basic customer journeys
- Email templates
- Small business contact lists
- Businesses already using Mailchimp integrations
AI workflow: Generate several subject lines and preview-text variations for the same campaign. Test the strongest versions rather than selecting one based only on personal preference.

4. Brevo
Brevo is useful for businesses that need marketing emails, transactional communication, contact management, and SMS capabilities in one platform.

Best for:
- Marketing and transactional email
- Email and SMS communication
- Basic contact management
- Appointment or account notifications

- Service-based companies
AI workflow: Draft short transactional messages for confirmations, reminders, account updates, and follow-ups. Review every message for clarity and accuracy before adding it to an automation.
Why it stands out: Brevo combines several communication and customer-management features that would otherwise require separate tools.
5. Kit
Kit, formerly known as ConvertKit, is designed for creators who build audiences and sell digital products, subscriptions, courses, memberships, or professional services.
Its tagging and sequence features make it suitable for organizing subscribers according to their interests, purchases, and engagement.
Best for:
- Content creators
- Coaches and educators
- Digital products
- Online courses
- Lead magnets
- Tag-based email sequences
- Newsletter businesses
AI workflow: Turn a blog post, webinar, podcast episode, or guide into a short email sequence that introduces the topic, teaches one useful idea, and recommends the next step.
Why it stands out: Kit focuses on the specific needs of creators rather than trying to serve every type of business.
6. HubSpot
HubSpot is a strong option when email marketing needs to connect directly with customer relationship management.
Businesses can use CRM information to organize contacts, track lead activity, create follow-up workflows, and align marketing campaigns with sales processes.

Best for:
- CRM-connected email marketing
- B2B lead nurturing

Klaviyo is designed for ecommerce businesses that need detailed customer data, behavioural segmentation, purchase-based triggers, and revenue attribution.

However, businesses should compare its total cost and required features with alternatives such as Omnisend before choosing a platform.
Best for:
- Ecommerce segmentation

ActiveCampaign is suitable for businesses that need more complex marketing and sales automation.
Its workflow builder can support conditional paths, lead scoring, tags, behavioural triggers, CRM-related processes, and longer customer-nurturing sequences.
The platform is more appropriate for teams with a clear automation strategy than for beginners who only need a basic newsletter.
Best for:
- Advanced marketing automation
- B2B lead nurturing
- Multi-step workflows
- Conditional customer journeys

AI workflow: Describe the goal of an automation in plain language, map the required stages, and generate draft messages for each point in the customer journey.

AI workflow: Turn one content topic into a newsletter, educational follow-up, promotional email, and re-engagement message.

10. ChatGPT or Claude
ChatGPT and Claude are not complete email marketing platforms. They cannot independently manage subscriber consent, send campaigns, process unsubscribes, or replace a dedicated email service provider.
However, they can support almost every content-related part of an email marketing workflow.
Businesses can use them to brainstorm campaigns, draft messages, improve calls to action, create subject-line variations, summarize customer feedback, and plan email sequences.
Best for:
- Subject-line ideas
- Campaign planning
- Welcome-sequence drafts
- Newsletter summaries
- Calls-to-action
- Segmentation ideas
- A/B testing variations
- Rewriting existing emails
AI workflow: Provide the AI tool with your audience, offer, campaign objective, brand voice, and required action. Ask for several variations, then review the output before adding it to your email platform.
Important: Always review AI-generated marketing emails before sending them. Check product claims, prices, links, deadlines, personalization fields, and legal or compliance information.
The First Automation a Small Business Should Build
Most beginners should start with a three-email welcome sequence.
Email 1: Welcome and Set Expectations
Thank the subscriber for joining and explain what they can expect from your emails.
Give them the resource, discount, guide, or information that encouraged them to subscribe.
Email 2: Provide Immediate Value
Share a useful tip, article, checklist, video, or product recommendation related to the subscriber’s original interest.
Avoid making every welcome email a sales message.
Email 3: Introduce the Next Step
Invite the subscriber to take one clear action.
That action could be:
- Visiting a product page
- Reading a guide
- Booking a consultation
- Comparing software
- Replying to the email
- Following your business on social media
- Making a first purchase
How to Use AI for Subject-Line Testing
AI can generate many subject-line ideas quickly, but campaign data should determine which version performs best.
Ask the AI to create different styles, including:
- Direct
- Benefit-focused
- Curiosity-driven
- Question-based
- Personalized
- Urgent without appearing spammy
- Short and mobile-friendly
Test one major variable at a time. When the subject line, preview text, email body, offer, and call to action all change simultaneously, it becomes difficult to understand what caused the result.
Useful Email Segments to Create
Small businesses do not need dozens of segments at the beginning.
Start with groups such as:
- New subscribers
- First-time customers
- Repeat customers
- High-value customers
- Leads grouped by source
- Subscribers who clicked a specific link
- Inactive subscribers
- Customers interested in a particular product
- Customers who abandoned a cart
- Customers who have not purchased recently
Relevant segmentation often improves email performance more effectively than producing more generic AI-generated content.
Email Deliverability Basics
Before increasing your email volume:
- Verify your sending domain
- Configure SPF, DKIM and DMARC where appropriate
- Use clear unsubscribe links
- Remove invalid addresses and hard bounces
- Avoid buying email lists
- Send emails only to people who have provided the appropriate permission
- Clean inactive contacts when necessary
- Avoid misleading subject lines
- Monitor spam complaints
- Do not overwhelm new subscribers with excessive messages
AI can help create campaign content, but it cannot compensate for poor consent practices, weak list quality, or damaged sender reputation.
Common Email Automation Mistakes
Avoid these mistakes when setting up your campaigns:
- Creating complicated workflows before testing a simple sequence
- Sending generic AI-written content without editing it
- Ignoring mobile users
- Failing to test links and personalization fields
- Over-segmenting a small list
- Tracking only opens instead of clicks and conversions
- Sending too many promotional emails
- Forgetting to update old automated messages
- Using outdated prices, product information or discount codes
- Ignoring email and SMS consent requirements
Final Recommendation
For ecommerce businesses, Omnisend is our leading choice because it combines email, SMS, segmentation, ecommerce workflows, and AI-supported features in one platform.
Its free five-day migration offer can also make it easier for eligible businesses to move from Klaviyo or another email service without manually rebuilding every major workflow.
Beginners and service businesses should consider MailerLite or Brevo. Creators should compare Kit, while B2B teams that depend on CRM data should consider HubSpot.
ActiveCampaign is the stronger option for businesses that need complex automation, conditional workflows, and lead scoring.
The best tool is ultimately the one that fits your audience, business model, technical ability, marketing channels, and current stage of growth.
