Choosing email marketing software comes down to five decisions: how the tool bills as your list grows, how much automation you will really build, which systems it must connect to, how well it supports deliverability and compliance, and how easy it is for the people who will use it every week. Price the platform at the list size you expect in a year, and test it with a real campaign before you commit.
The good news is that the core features are similar across the category. Almost every tool has a drag-and-drop editor, signup forms and basic automation. The differences that matter show up in billing, data, limits and support.
Be clear about what email has to do for you
Start with the job, not the feature list. The same tool can be a perfect fit for one business and a poor one for the next.
- Service businesses and local companies usually need a monthly update, a welcome series and a way to collect leads from the website.
- Online stores need flows triggered by orders, carts and browsing, with product blocks pulled from the catalog.
- Creators and publishers need tag-based subscriber management, paid products and a simple, text-first editor.
- B2B companies need lead scoring, form tracking and a clean handoff to sales in a CRM.
Write down the three emails or flows that drive most of your results today, or that you plan to build first. Every tool you shortlist should handle those three without workarounds.
Understand how billing scales
Sticker prices on email tools are almost always for the smallest list size. The number that matters is what you will pay in 12 months. Vendors use three main models:
- By subscribers or contacts. MailerLite, Mailchimp and Kit price by list size. MailerLite starts at $12 a month and Mailchimp from $13, and both rise in steps as your list grows.
- By active profiles. Klaviyo prices by active profiles, starting from $20 a month, so the bill tracks the customers you can actually email.
- By emails sent. Brevo prices mainly by send volume, from $9 a month, which favors large lists that are emailed a few times a month.
Watch the limits inside each plan
Plan limits often matter more than price. Mailchimp’s paid plans cap monthly sends at a multiple of your contact count (10 times on Essentials, 12 on Standard and 15 on Premium) and bill overages. Its Essentials plan allows automation flows of up to four steps, while Standard allows up to 200 flows. MailerLite’s Comfort plan caps active automations at 50, forms at 10 and landing pages plus websites at 10 combined, while its Power plan removes those caps.
Also check who counts toward your bill. Unsubscribed, bounced or duplicate contacts can still count on some platforms. Cleaning your list before you import it is the cheapest saving you will find.
Match automation depth to what you will build
Automation is where most businesses overspend. Paying for branching journeys, lead scoring and goals you never set up is common, and those features usually sit on higher plans.
- Basic: a welcome series, a lead magnet delivery and a birthday or anniversary email. Every tool on the market handles this, including free plans such as MailerLite’s, which includes three automations.
- Intermediate: segments based on clicks and tags, re-engagement flows, and simple ecommerce flows such as abandoned cart. MailerLite Comfort, Mailchimp Standard and Kit’s paid plans fit here.
- Advanced: branching paths with conditions, lead scoring, site tracking and sales pipeline updates. ActiveCampaign is built for this level, and Klaviyo leads for store data.
Be honest about who will build and maintain these flows. A complex automation that nobody understands after the person who built it leaves is worse than a simple one that works.
Check the integrations you rely on
Email software is only as good as the data flowing into it. Before you sign up, confirm a native connection to each of these, not just a route through a third-party connector:
- Your website platform, such as WordPress, Squarespace or Webflow, for forms and popups.
- Your store, such as Shopify or WooCommerce, if you sell online. Klaviyo reads order and browsing data directly, which is why online stores rank it so highly.
- Your CRM, such as HubSpot or Salesforce, if sales follows up on leads.
- Your payment or booking tools, such as Stripe or a scheduling app, if they trigger emails.
Mailchimp has the largest integrations marketplace of the tools we rank, which helps if you use less common software. Zapier or Make can fill gaps, but every connector is one more thing that can break, and the usage fees add up.
Get deliverability and compliance right
The best editor in the world is useless if your emails land in spam. Since 2024, Gmail and Yahoo have required bulk senders to authenticate their domain with SPF, DKIM and DMARC, offer one-click unsubscribe and keep spam complaint rates low. Every tool on our list supports this setup, but some guide you through it better than others. Ask each vendor how they help you set up a custom sending domain and monitor complaints.
Know the rules that apply to your list
- CAN-SPAM (US): include a physical mailing address and a working unsubscribe link, and honor opt-outs promptly.
- GDPR (EU and UK): you need a lawful basis, usually consent, for each subscriber, and records that show it.
- CASL (Canada): requires express or implied consent before you send commercial email.
Look for double opt-in, consent fields on signup forms, a preference center so subscribers can choose topics instead of leaving entirely, and easy export of consent records. MailerLite added a preference center to its Comfort plan, for example.
Look at seats, support and switching costs
Team access varies more than you might expect. Mailchimp includes 3 seats on Essentials, 5 on Standard and unlimited seats on Premium. MailerLite’s free plan includes 2 user seats. If several people write, approve or report on campaigns, add their seats to your comparison.
Support is similar. Mailchimp offers 24/7 email and chat support on paid plans and phone support on Premium. MailerLite offers live chat on Power and on Comfort plans of 50,000 subscribers or more, with email support below that. If your team is not technical, live help during setup is worth paying for.
Judge ease of use by who sends
The person who sends the weekly campaign matters more than the feature list. If that is an office manager or a founder with ten spare minutes, a clean editor and clear menus beat advanced options. MailerLite is known for an editor that new users learn quickly, while ActiveCampaign takes longer to set up well. Have the actual sender build one campaign in each trial and ask which tool they would rather use every week.
Finally, think about leaving. Every tool lets you export contacts as a CSV, but automations, templates and engagement history usually stay behind. Pick a tool you can see yourself using for at least two years.
Run a trial with real campaigns
Free plans and trials make testing easy. MailerLite and Mailchimp both have free plans for very small lists, Kit’s free plan covers up to 10,000 subscribers, and Mailchimp offers a 14-day trial on Essentials and Standard. Use that time to do real work:
- Import a clean copy of your list and check how the tool counts contacts.
- Authenticate your sending domain with SPF, DKIM and DMARC.
- Rebuild your best-performing email and your welcome automation.
- Connect your website form and your store or CRM.
- Send a test campaign to a small segment and review the report.
- Ask support one real question and note how long the answer takes.

Frequently asked questions
Should you start on a free email marketing plan?
Yes, if your list is small and you mainly want to learn the tool. MailerLite’s free plan covers 250 subscribers and 2,500 emails a month, and Mailchimp’s covers 250 contacts and 500 sends. Expect to move to a paid plan once your list grows or you need more automation, forms or landing pages.
How big does your list need to be before cost matters?
Cost starts to matter at a few thousand contacts, when list-based pricing climbs in steps. Price each shortlisted tool at the list size you expect in a year, and include extra seats and add-ons. A platform that looks cheap at 500 subscribers can cost far more than a rival at 10,000.
Do you need a dedicated IP address for email?
Most small and midsize senders do not. Shared IP pools managed by the platform are fine for lower volumes, and a dedicated IP only helps if you send large, steady volumes. Authenticating your own domain with SPF, DKIM and DMARC does far more for deliverability at typical small business volumes.
How long does it take to set up a new email platform?
A basic setup with a list import, domain authentication, a signup form and a welcome email takes a day or two. Rebuilding several automations, templates and integrations can take a few weeks. If you are moving from another tool, warm up sending gradually rather than emailing your full list on day one.
