Compare the complete sending cost
Unlimited emails with your own server, from €12/month
Starter includes 10,000 active subscribers, one connected server and 25,000 hosted emails per billing month. Emails actually sent through your connected server have no monthly platform email quota and do not use hosted credits.
Your VPS is billed separately. Warm-up, fair use, server capacity, subscriber limits and other plan limits apply. A connected server does not guarantee inbox placement.
See how own-server sending worksSendy: the published cost model
Sendy lists its software at US$69 as a one-time licence for one installation domain. Application hosting and delivery-provider charges are additional. Optional AI and installation services cost extra. Check the current licence and upgrade terms rather than treating the purchase price as a total lifetime operating cost.
SendMailOS prices are in EUR. Competitor USD examples are labelled US$ and are not converted. Billing terms, taxes, selected features and usage can change the final invoice. Entry examples are not equal-capacity quotes.
Match the same audience and sending pattern
For 10,000 active subscribers and 100,000 monthly recipient sends, estimate a Sendy installation’s hosting plus the selected SES or SMTP-provider usage, and spread the licence cost over your chosen budgeting period. Compare that with SendMailOS’s recurring plan plus VPS costs. Currency conversion, taxes and labor assumptions must be consistent.
A transparent SendMailOS example
10,000 active subscribers, 100,000 own-server recipient sends per month and one suitable server: Starter €12 + an illustrative €8 monthly VPS estimate = €20/month. This assumes the server can handle that volume under warm-up and sending safeguards. It is not a VPS quote, a capacity promise or a hosted-send quote. The separate Starter hosted allowance remains 25,000 emails.
Which model fits your team?
Consider SendMailOS
Consider SendMailOS when you want the campaign application managed for you and are comfortable operating only the connected delivery server when choosing that route.

Evaluate Sendy when hosting and maintaining the newsletter application yourself is part of your requirements. Include the time needed for updates, database operations, backups and sending-provider setup in the comparison.
Test before switching
Record the current behavior
List required integrations, audience fields, message types, exclusions, schedules and reports. Preserve consent records and suppression states separately from active subscribers.
Rebuild a representative example
Rebuild one newsletter and one follow-up sequence. Preserve your active and excluded audiences separately, verify personalized links and unsubscribe behavior, then check a controlled test message through the selected delivery route.
Compare observed outcomes
Check the received message, delivery events, links, personalization, unsubscribe and any reply path using mailboxes you control. A recorded open is not proof that a person read the email; an accepted message is not an inbox-placement guarantee.
Move only after the test passes
Verify your domain and selected route, reconcile audience counts and pause the previous workflow before enabling its replacement. Plan a gradual sending transition and retain the source export for recovery.

Check every plan limitQuestions before you choose
Is SendMailOS own-server sending the same as self-hosting Sendy?
No. With SendMailOS, the application stays managed while your connected server handles delivery. With Sendy, you host the newsletter application yourself.
Is Sendy’s one-time fee the whole sending cost?
No. Include application hosting, the email provider’s usage, maintenance and any optional services. Review current licence and upgrade terms when budgeting.
Does connecting a server remove all SendMailOS limits?
No. Own-server email volume has no monthly platform email quota, but your subscriber, connected-server and other plan limits remain. Your VPS costs, capacity, warm-up and sending safeguards also apply.
