Is Mailgun worth the price?

78/100

Mailgun's pricing is competitive, especially for developers needing high volume.

The Foundation tier at $35 for 50,000 emails is a good entry point, but the per-email overage at $1.30 per 1,000 is a bit high. The Scale tier offers better value at $90 for 100,000 emails with a lower overage.

It's best for developers and businesses with predictable to high email sending needs.
