Unlike Bird’s evolving CRM suite, Mailgun is purpose-built for infrastructure-grade email at scale with best-in-class tools across validation, routing, monitoring, and performance insights.
Mailgun also avoids Bird’s a la carte pricing approach: every plan includes support, ensuring even users on Mailgun’s smaller tier plans get timely help from actual humans via support tickets.
Pricing overview
| Emails / month | Approx. cost | Notes |
| Up to 10k | Free | Includes sending, API access, logs, and basic analytics |
