Mautic is genuinely free software and one of the most capable open-source marketing automation platforms ever shipped. It is also, for most senders in the bring-your-own-Amazon-SES category, the most operationally expensive choice once you measure cost in engineering hours rather than license fees. The official requirements page is blunt: shared hosting is unsuitable, you need a VPS or dedicated server, PHP 8.2 to 8.4, MySQL 5.7+ or MariaDB 10.2+, and a long list of PHP extensions. That is before you write a single email.
This guide compares Mautic against Mailblast for teams who already plan to send through Amazon SES. If you are weighing other self-hosted options, the Sendy vs Mailblast and MailWizz vs Mailblast comparisons cover the lighter-weight PHP scripts in the same category.
What Mautic is and what it actually does
Mautic positions itself as "The World's Largest Open Source Marketing Automation Product" and is used by over 40,000 companies according to the project's own homepage. The current community release is Mautic 7.1.2 (May 2026), built on PHP and Symfony. It is not an email tool with extras bolted on, it is a full marketing automation platform that happens to send email.
Out of the box, Mautic ships with a campaign builder with decision branches, drag-and-drop email and landing page editors, web forms with progressive profiling, lead scoring, segment-based automation, a REST API, and omnichannel messaging across email, SMS, WhatsApp, and web notifications. That breadth is the appeal. It is also the source of the operational weight: every one of those subsystems has its own background jobs, database tables, and failure modes.
True total cost of ownership: dollars vs operational hours
License cost is zero. Total cost of ownership is not. A production Mautic install on a $40-per-month VPS, plus Amazon SES at $0.10 per 1,000 emails, plus a fractional sysadmin at the Stack Overflow 2025 median developer rate of roughly $75 per hour, adds up faster than the sticker price suggests. The chart below estimates a realistic first-year spend for a list of 15,000 contacts sending around 60,000 emails per month.
The license line is zero, exactly as advertised. The operations line is where Mautic absorbs the savings: PHP minor-version upgrades, MySQL slow-query investigation, queue worker supervision, and the inevitable "campaigns stopped firing because cron drifted" Tuesday morning. Even at a conservative one hour per week, the labor line dwarfs Mailblast's entire subscription.
Features head-to-head
The two products do not overlap cleanly. Mautic 7.1.2 ships landing pages, web forms with progressive profiling, lead scoring, and omnichannel sends across email, SMS, and web notifications (Mautic, 2026). Mailblast ships drag-and-drop email, automation, and analytics on top of your own Amazon SES account, and stops there. The table below maps the gap.
| Capability | Mautic 7.1 | Mailblast |
|---|---|---|
| Hosting model | Self-hosted (VPS or dedicated) | Hosted SaaS, your AWS account |
| Software license | ✓ Free (GPLv3) | Free tier, paid from $10/mo |
| Stack required | PHP 8.2-8.4, MySQL 5.7+, npm, cron | ✓ None |
| Email editor | Built-in drag-and-drop builder | BeeFree drag-and-drop with Liquid |
| Campaign automation | ✓ Decision-branch builder | Welcome, drip, list triggers |
| Landing pages | ✓ Built-in | ✗ No |
| Web forms | ✓ Progressive profiling | Limited |
| Lead scoring & CRM sync | ✓ Native | ✗ No |
| SMS / WhatsApp / push | ✓ Omnichannel | ✗ Email only |
| A/B testing | ✓ Yes | ✗ No |
| Mailblast | Hosted, no ops, BeeFree editor, automation included on every paid plan, no platform branding from the first paid rung, billed monthly. AWS SES bills you directly at $0.10/1k. | |
| SES integration | SMTP or SES API transport | ✓ Native, manages your account |
| Suppression list sync | Manual or plugin | ✓ Automatic with SES |
| Upgrade path | Manual, version-pinned | ✓ Continuous |
Mautic clearly wins on breadth. If you need a landing page, a progressive form, and a campaign that triggers an SMS after an email open, that is a single Mautic instance. To do the same with Mailblast, you would pair it with a separate landing-page tool and a separate SMS provider. The question is whether you actually need that breadth or whether the email-and-automation slice covers your real campaigns.
When Mautic is the right call
Mautic earns its operational tax in three specific situations: an in-house team already running PHP and Symfony in production, a regulatory or procurement requirement that rules out closed-source SaaS, or a campaign mix that genuinely needs decision-branch automation across email plus SMS, WhatsApp, and web notifications - the omnichannel slice listed on the Mautic project homepage (Mautic, 2026).
The first is when you genuinely have in-house PHP and Symfony capability. A team that already runs a Symfony app, monitors PHP-FPM, and has opinions about MySQL InnoDB tuning will not find Mautic's stack alien. The marginal cost of one more PHP service is small for them, and the source-code access lets them customize freely.
The second is when source-code custody is a regulatory requirement. Some regulated industries, public-sector tenants, and EU data-residency mandates push organizations toward self-hosted software where the deployment lives entirely inside their own cloud account. Mautic's GPLv3 license and self-hostable architecture satisfy procurement teams that will not accept any closed-source SaaS regardless of where data is stored.
The third is when you actually need omnichannel automation across email, SMS, WhatsApp, and web notifications with decision-branch logic. That is Mautic's home turf. A focused email tool like Mailblast can integrate with an SMS vendor, but you will be wiring it together, not configuring a unified campaign.
When Mailblast is the right call
For everyone else who lands on the Mautic download page, the honest answer is usually "do not run this." Mailblast targets the specific gap Mautic asks you to fill yourself: a single-brand operator who wants Amazon SES economics at $0.10 per 1,000 emails (AWS, 2026), drag-and-drop campaigns through a BeeFree editor, and welcome-and-drip automation, without becoming a part-time PHP sysadmin.
That profile covers most newsletter publishers, SaaS lifecycle senders, ecommerce stores under a few hundred thousand contacts, and consultants running client newsletters. AWS bills you directly for sending at $0.10 per 1,000 emails. Mailblast's entry paid plan is $10 per month for 1,000 contacts, on a 32-rung ladder up to 500,000, and includes automation and unbranded sending; the free tier covers 1,000 contacts and 10,000 emails per month if you want to start before paying anything. There is no server to patch, no PHP version to track, no cron job to babysit.
The trade-off is real: no landing pages, no A/B testing, no SMS, no multi-brand workspaces. If those are deal-breakers, you are not the target customer. If they are not, the operational savings are large enough that the Mautic license cost of zero stops being a meaningful advantage.
The verdict
Choose Mautic if you have devops budget, want every channel in one tool, or have a procurement requirement for open-source self-hosted software. For 80% of senders looking at Mautic because "it is free," Mailblast from $10 per month plus AWS SES at $0.10 per 1,000 will end the year ahead on total cost, deliver mail through the same Amazon SES infrastructure, and leave your evenings alone.
Frequently asked questions
Is Mautic really free?
Mautic's software license is free under the GPLv3, with no per-contact or per-email fees. The real costs are infrastructure (a VPS or dedicated server, not shared hosting per the official requirements page) and operations: PHP runtime patches, MySQL tuning, cron jobs, Mautic upgrades, and occasional incident response when queues stall.
Can Mautic send through Amazon SES?
Yes. Mautic supports Amazon SES as a delivery transport via SMTP or the SES API, so you keep the $0.10 per 1,000 emails AWS pricing. The trade-off is that you also keep responsibility for warming the IP, monitoring bounces, and reconciling SES suppression lists with Mautic's contact database yourself.
How much server power does Mautic need?
The official requirements page rules out shared hosting and recommends a VPS or dedicated server with PHP 8.2 to 8.4, MySQL 5.7+ or MariaDB 10.2+, and required extensions including xml, imap, zip, intl, curl, gd, mbstring, and bcmath. Most production deployments start at 4 GB RAM and scale up as segment recalculations grow.
Is Mailblast open source like Mautic?
No. Mailblast is a closed-source hosted product that manages your own Amazon SES account on your behalf. You bring AWS credentials and AWS bills you directly at $0.10 per 1,000 emails; Mailblast handles the application layer, editor, automation, and analytics so you do not run PHP or MySQL yourself.
When should I pick Mautic over Mailblast?
Pick Mautic if you have in-house PHP and devops capacity, need landing pages and forms built into the same tool, require full source-code access for compliance, or run complex multi-channel campaigns with SMS and web notifications. Pick Mailblast if you want SES economics for a single brand without running a server.
