More domains and longer logs than Mailgun Basic, with no plan.
Mailgun's Basic plan allows one domain and keeps logs for a day. More domains and longer history mean a bigger plan. On toSend they're included, and you pay only for what you send.

Switching from Mailgun
You don't have to move everything at once. toSend runs alongside Mailgun, so you can move one site or app first and keep the rest where they are.
Full migration guide: field map, SMTP settings and webhook events
- Create a toSend account and add your domain. Our DNS records use their own names (
tosend._domainkeyandsend), so they sit alongside your Mailgun records and nothing stops working while you test. - Wait for the domain to verify. We check every 10 minutes and activate it as soon as the records are visible. On Cloudflare, one click adds them.
- Point one site or app at toSend: choose toSend in FluentSMTP on WordPress, change the SMTP host and password, or swap the API call for one of our SDKs.
- Send a test and find it in your toSend logs. When you're happy, move the next site. Keep your Mailgun account until the last one has moved.
