Worth knowing

- Inbox placement tests and reputation monitoring are a separate product, Mailgun Optimize.
Resend
- Billing is monthly only; there are no annual plans or yearly discounts.
- There is no plan between Free and the $20 Pro plan, and the free plan caps sending at 100 emails a day.
- Dedicated IPs cost $30 a month and need the Scale plan and more than 3,000 emails a day; SSO is a $150 a month add-on on Scale.
- Marketing email is priced separately by contacts, from $40 a month for 5,000; broadcasts do not use the transactional quota.
