For small businesses sending 5,000 emails a month, SendGrid or Mailchimp are fine. But if you are a high-volume sender (1M+ emails/month), ESPs become incredibly expensive and risky.
Cost Comparison (Monthly)
| Volume | SendGrid Pro | Mailgun Scale | Self-Hosted (DMARCMaster) |
|---|---|---|---|
| 100,000 | $89.95 | $90.00 | $50 - $100 (Server Cost Only) |
| 500,000 | $449.00 | $400.00 | |
| 1,500,000 | $900+ | $1,200+ | |
| Unlimited | $$$$ | $$$$ |
Why Switch?
- No Bans: SendGrid can suspend your account instantly if you get a few spam complaints. On Self-Hosted, YOU own the server. Nobody can ban you.
- Data Privacy: Your email list stays on your server. No third party scans your data.
- Dedicated IPs: You don't share reputation with other spammers.
