Email marketing is one of the highest-return channels for a small business, but paying for a platform before you have an audience is wasteful. Fortunately, several reputable tools offer genuinely useful free tiers for small lists — typically covering a few hundred to a couple of thousand subscribers. The trick is choosing a free plan that fits how you actually send, not just the one with the biggest headline number.

Start by comparing what matters beyond the subscriber cap. Check the monthly send limit, because a plan allowing a thousand subscribers but only a few hundred sends per month will choke a weekly newsletter. Check whether automation is included — welcome sequences and basic drip campaigns are where email marketing earns its keep, and some free plans strip them out. Check the branding rules: some free tiers require the provider's logo in your emails, which is fine for a hobby list but less so for a business. And check the upgrade path, because you will eventually outgrow the free tier and a painful migration can cost you subscribers.

Several established platforms are worth evaluating. Mailchimp's free tier is the best-known option and suits small lists with simple needs, though its automation on the free plan is limited. Brevo offers a free plan based on daily send limits rather than list size, which suits senders with a small list who email frequently. MailerLite's free tier is popular with creators for its clean editor and automation basics. ConvertKit offers a free plan aimed at creators with landing pages and simple sequences. Rather than picking on reputation, sign up for two finalists, import a small test segment, and send a real campaign to yourself to judge the editor and deliverability.

Deliverability details are easy to skip and expensive to ignore. Set up a custom sending domain and proper authentication records before your first real campaign — emails sent from a free provider domain land in spam more often. Warm up gradually: start with your most engaged contacts rather than blasting your entire list on day one. And keep your list clean from the start by using double opt-in and removing hard bounces promptly. A small, engaged list on a free tier will outperform a large, stale list on a paid plan every time.

Finally, know when the free tier has done its job. Upgrade when you consistently hit send limits, need automation the free plan lacks, or want to remove provider branding. That is a good problem — it means the list is working. Until then, the right free tier lets a small business build a real email channel for nothing but the effort of writing good emails.

Before committing to any free tier, run through this short checklist. Does the plan include signup forms and landing pages, or will you need a separate tool for list building? Can you segment subscribers, so new subscribers get a welcome sequence while existing ones get your newsletter? Does the plan include basic reporting, so you can see open rates and click rates and learn what your audience responds to? Can you export your list at any time without paying — a crucial freedom, because a list you cannot export is a list you do not truly own. Finally, is there a clear published price for the next tier up, so you can plan the upgrade cost? If a tool fails on export or hides its pricing, think twice before building your audience on it. Also consider deliverability support: does the free plan include help with domain authentication, and does the provider maintain a good sender reputation? These details decide whether your emails reach inboxes or spam folders, and they matter far more than a slightly larger subscriber cap.
