How to Choose Email Marketing Software: A Practical Framework

Most email marketing platforms can send a newsletter, collect signups and run a welcome sequence. That is why comparing feature lists rarely settles the question. The useful differences are in how a tool charges you as you grow, what the free plan really allows, how deep the automation goes, and how easy it is to leave. This guide gives you a framework for weighing those factors, a short checklist, and a section matching common situations to the type of tool that tends to fit.

Start with what you actually need

Before comparing tools, write down three things:

1. What you will send. A weekly newsletter, product announcements, automated onboarding, abandoned-cart emails, or a mix.
2. How big your list is now, and in a year. A realistic estimate, not a hope.
3. Who will use the tool. Just you, or a team that needs separate logins.

Keep this list next to you as you compare. It stops you from paying for features you will not use or choosing a free plan you will outgrow in two months.

The decision framework

1. Pricing model: contacts, subscribers or emails sent

This is the most important factor for long-term cost, and the one people most often skip.

Common pricing models

Criteria	How it works	Suits	Watch out for
By subscribers	You pay for the number of active subscribers	Regular senders with a growing list	Costs rise with list size even if you send rarely
By contacts	You pay for stored contacts, which may include non-subscribers	Teams using the audience as a light CRM	Check whether unsubscribed contacts still count
By emails sent	You pay mainly for sending volume	Large lists that are emailed infrequently	Costs rise quickly if you send often

MailerLite and Kit price paid plans by subscribers, Mailchimp and ActiveCampaign by contacts, and Brevo mainly by email volume (check its current terms). Run your own numbers: list size multiplied by how often you send tells you which model favors you.

2. Free plan limits

Free plans differ more than their headline numbers suggest. Look at:

• Audience cap (subscribers or contacts)
• Monthly and daily sending limits
• Number of automations and steps
• Forms and landing pages
• User seats
• Support (often knowledge base only)
• Branding in your emails

For example, MailerLite’s and Mailchimp’s free plans both stop at 250 subscribers or contacts, but MailerLite allows 2,500 emails a month against Mailchimp’s 500. Kit’s free plan covers up to 10,000 subscribers but does not include visual automations or sequences. Brevo’s free plan allows 300 emails per day.

3. Editor

If you send designed newsletters, you want a reliable drag-and-drop editor. If you prefer personal, text-heavy emails, a simple editor matters more. If a developer is involved, check for custom HTML. Build one real email in each tool on your shortlist; it reveals more than any screenshot.

4. Automation depth

Simple automation means a welcome sequence and maybe a birthday email. Deep automation means branching paths, multiple triggers, conditions based on behavior and integration with sales data. Write down the most complex workflow you will realistically need in the next year (a welcome email sequence is a good starting point), then check that the plan you can afford supports it. Automation is often the feature most restricted on free and entry plans.

5. Landing pages and forms

Many platforms include signup forms, pop-ups and landing pages. If you do not have a website yet, or want to avoid a separate page builder, these can save money. Check how many you get on each plan.

6. E-commerce

If you sell online, check for a direct integration with your store platform (Shopify, WooCommerce or others), so purchase data can trigger emails and segment customers. If you sell digital products or paid newsletters, see whether the platform can handle payments itself.

7. Deliverability tools

No platform guarantees the inbox, but the good ones make it easier: guided domain authentication (SPF, DKIM, DMARC), automatic bounce handling, one-click unsubscribe support and clear reporting. Our deliverability checklist explains what each of these means.

8. Support

Free plans often come with self-service help only. If you want to reach a person, check which plan includes email or live chat support, and in which hours and languages.

9. Migration and export

Before you import a single contact, check that you can export everything later: contacts, consent status, tags or groups, and ideally campaign reports. A tool that is easy to leave is a safer tool to join.

10. Team seats

If several people will work in the account, check how many user seats each plan includes and whether roles or permissions are available. Sharing one login is a security risk and often against terms of service.

Quick checklist

• Pricing model favors my list size and sending frequency
• Free or entry plan covers my real sending volume
• Editor suits the kind of emails I send
• Automation on my plan can build my most important workflow
• Forms and landing pages included, if I need them
• Integration with my store or payment setup exists
• Domain authentication and unsubscribe handling are well supported
• Support level matches how much help I expect to need
• Full contact export is available
• Enough seats for everyone who needs access

Match your situation to a type of tool

These are starting points rather than verdicts. Each description reflects the provider’s published plans and features as of October 2026.

Small business or newcomer wanting an all-round tool on a budget

MailerLite is worth a close look. Its free plan includes 250 subscribers, 2,500 emails a month, 2 seats, 3 automations, 3 forms, a landing page and A/B testing. Paid plans (Comfort from $12 per month, Power from $25 per month) are priced by subscribers and add more sending, support and automation options. It also offers a website builder and integrations with Shopify, WooCommerce and Stripe. Its HeyLite Intelligence AI tools include a subject line generator and an MCP server for ChatGPT, Claude and Cursor on every plan. Account approval is automatic at signup, and new accounts get a 14-day free trial of premium features. See our MailerLite review and pricing breakdown.

Teams already familiar with a widely used platform

Mailchimp offers a tiered structure (Free, Essentials, Standard, Premium) priced by contacts, with generative AI features from Standard up and multivariate testing on Premium. Essentials and Standard have 14-day trials. Its free plan is tighter on sending (500 per month, 250 per day, 1 seat). Our MailerLite vs Mailchimp comparison goes into detail.

Creators, writers and solo publishers

Kit (formerly ConvertKit) is built around creators. Its free plan covers up to 10,000 subscribers with unlimited forms, landing pages and broadcasts, plus tagging and digital products. Visual automations and sequences require a paid plan (Creator or Pro), priced by subscriber count.

Large lists you email infrequently

Brevo (formerly Sendinblue) prices paid plans mainly by email volume rather than contacts, which can suit large lists that receive occasional campaigns. Its free plan allows 300 emails per day. Check Brevo’s current terms, as we verified fewer details for it.

Sales-driven businesses that need CRM and complex automation

ActiveCampaign focuses on multi-step automation and CRM features. There is no free plan, but there is a 14-day free trial. Plans (Starter, Plus, Pro, Enterprise) are priced by contacts.
