If you send tens of thousands of emails a month, you have probably compared hosted senders such as SendGrid, Mailgun or Amazon SES with running your own mail server. Both routes work. They trade money for effort in different ways.
Where SaaS costs add up
Hosted senders usually charge per message or by tier, so cost rises with volume. You may also share IP reputation with other customers, and your account can be reviewed or limited by the provider's policies.
What self-hosting gives you
- Fixed cost: you pay for a VPS and IP addresses, not per message. TurboMTA adds a one-time licence instead of a monthly fee.
- Your own IP reputation: good practice stays yours, and so does the responsibility.
- Control: rate limits, IP pools and routing are yours to tune.
What it costs you
Running your own MTA means you handle DNS authentication (SPF, DKIM, DMARC, reverse DNS), IP warm-up, list hygiene and bounce handling. Many VPS providers also block outbound port 25 until you ask them to open it. Deliverability is never guaranteed: it depends on your lists, content and reputation.
When self-hosting is the wrong choice
If you send low volume, have no one to look after the server, or need a vendor to manage reputation for you, a hosted sender is usually simpler.
