Billing terms, taxes, promotions, contact tiers, and selected extras may change the final price. SendMailOS own-server delivery still requires your paid plan, VPS costs, and sending safeguards.

Choose SendMailOS when…
Your email work includes both sending to subscribers and managing the messages they send back. You want developers and the campaign team to use the same platform.
MailerLite may still fit when…
Your current website, signup forms, or product-selling setup depends on MailerLite. A replacement should cover that whole process or leave the working parts in place.
Subscriber capacity and send capacity are separate
A tool can have enough monthly sends and still be too small for your audience. Count both. A list of 800 subscribed contacts with one monthly newsletter needs at least 800 eligible contacts and 800 email sends; a larger send allowance does not remove a subscriber cap.
Check the next step, too. If you add a welcome series, each email to each new subscriber uses more capacity. Keep a little room for tests and application messages. SendMailOS’s monthly credits are shared by the hosted sends that use that allowance, rather than a separate free budget for every feature.
Before you switch from MailerLite
Keep forms and signup sources visible
List every place a subscriber joins. Preserve consent, source information, and unsubscribe status when preparing your audience.
Recreate your reusable template
Build your header, content blocks, and footer in the editor. Send a mobile test and check every link.
Test the first welcome
Create one subscriber, run the sequence, and check its timing. Confirm that unsubscribing prevents later marketing messages.
Compare the whole setup
Keep working websites, forms, or sales tools until their replacements are tested. Switch email only when the new sending path is ready.
Questions before you choose
Does MailerLite still offer 12,000 free emails?
The current pricing and Free plan pages list 2,500 monthly emails for up to 250 subscribers. Older comparisons may show earlier allowances; use the current official plan details.
Can I use SendMailOS with my existing website?
SendMailOS Pixel can connect website activity with identified subscribers. Review the setup guide and validate the events you need. Do not assume an unlisted website integration exists.
Should I switch just for a larger free audience?
Audience capacity matters, but so do templates, automations, replies, and your existing tools. Test one complete signup-to-email journey before deciding.
