Compare email platforms
Compare SendMailOS with self-hosted Mautic for email workflows, application operations and delivery costs. Check the capabilities your team needs before switching.
The SendMailOS application stays managed. Operating a connected sending server does not self-host the application or all its data.
Mautic is free to download and use. Self-installation needs web-server, database, PHP and scheduled-job administration.
Evaluate campaigns, visual email workflows, Pixel audiences and native reply conversations against your use cases.
Mautic lists campaigns, email A/B testing, forms, landing pages, web tracking, scoring and a REST API.
Use hosted allowances or a connected sending server on the eligible paid plan.
Mautic’s documented default email transport is SMTP; the selected transport and provider need their own configuration.
Monthly subscription plus VPS costs for own-server delivery; check active subscribers and all feature limits.
Budget application hosting, email transport/provider costs, backups, updates, monitoring and any paid implementation/support.
Checked 24 October 2026 using the official sources below. This is a SendMailOS comparison, not an independent performance test.
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 worksMautic’s downloadable software has no licence fee. That is not a zero operating-cost quote: hosting, delivery, maintenance and optional managed services must be priced for your installation. Hosting-provider plans and commercial support are separate offers.
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.
For 10,000 active subscribers and 100,000 monthly recipient sends, estimate the complete Mautic installation and chosen delivery transport, including operational labor. Compare that with SendMailOS’s subscription and VPS estimate. A feature such as forms, scoring or landing pages should be tested explicitly if your current journey depends on it.
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.
Consider SendMailOS when you want a managed email workspace and a choice of hosted or own-server delivery. Test your campaign, workflow, tracking rules and reply handling before deciding.
Evaluate Mautic when self-hosting the application, extending it or using its broader lead-management model is central to your requirements. Check the supported version and your team’s operating capacity.
List required integrations, audience fields, message types, exclusions, schedules and reports. Preserve consent records and suppression states separately from active subscribers.
Inventory campaign decisions, timers, fields, scoring rules, forms and transport settings before moving. Rebuild one representative journey with a test audience. Validate exclusions and timezone behavior, then confirm event tracking and sending outcomes before disabling the old journey.
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.
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.

Every paid plan includes own-server access. More than 10,000 active subscribers or more than one connected server does not fit Starter. Domain, team, automation, API and other limits also apply.
Check every plan limitThe Mautic project states that its software is free to download and use. You still need to budget for hosting, delivery infrastructure, operations and any paid services you choose.
No. The SendMailOS application remains managed; the connected server handles its configured email delivery. Review the actual data flow for your requirements.
Do not assume a direct campaign conversion. Map triggers, decisions, timing, templates, fields and exclusion rules, then rebuild and test the supported behavior in the destination.
Reviewed by SendMailOS on 24 October 2026. Product documentation supports the scoped facts above; live behavior and suitability still need testing with your setup. Recheck current prices and limits before purchase.
