The Exit Question

Mailgun works. Leaving it is the hard part.

Teams rarely move off Mailgun because the API stopped working. They move because the plan tier jumped, because inbound routes grew into a parsing layer nobody owns, or because the answer to “what happens if we leave?” is a rewrite. Reloop keeps the same sending surface and removes that last answer.

Plan tiers, not usage

Basic covers 10,000 emails at $15/mo; the next real step is Foundation at $35/mo. Validation and dedicated IPs are priced on top. Reloop bills per send, and self-hosting removes the tier entirely.

Inbound that outgrew routes

Support inboxes and reply parsing start as one Mailgun route and end as a service. Reloop's agent inbox handles triage, spam scoring, and threading before the webhook fires.

Reputation you can take with you

Deliverability follows your domains and IPs, not the dashboard. Self-hosted Reloop attaches your own IPs directly to the MTA, so the sending identity stays yours.

Migrate in minutes

Switching from Mailgun to Reloop is straightforward. Keep your templates, swap the send path, and re-wire webhooks, without rewriting your product.

Connect from Mailgun

Step 1

Create a Reloop account and verify the domains you already send from with Mailgun. Keep both providers live while DKIM and SPF propagate.

5 min
acme.com
mail.acme.com
staging.acme.com
Confirm domains

Step 2

SMTP senders change host, port, and credentials, with no application rewrite. API senders swap the endpoint and map Mailgun inbound routes to Reloop handlers.

Step 3

Re-point event webhooks at Reloop, move suppression lists across, then shift traffic domain by domain until Mailgun is idle.

1 afternoon

The Reloop SMTP guide covers credential rotation without downtime. Reloop is not a drop-in Mailgun proxy, so plan a small client adapter for API senders.

FAQ

Mailgun vs Reloop FAQ

Reloop's agent inbox and webhook model cover reply handling and automated triage. Map your existing inbound URLs to Reloop handlers during migration.

Deliverability depends on domain reputation, content, and IPs, not the dashboard brand. Self-hosted Reloop lets you own IPs directly; hosted Reloop manages shared pools like other providers.

Mailgun Basic is $15/month for 10,000 emails and Foundation is $35/month for 50,000, with overage from $1.30 per 1,000. Reloop Pro is $10/month for 50,000 emails and Growth is $20/month for 100,000, with overage at $0.50 per 1,000. Self-hosted Reloop has no Reloop license fee; you pay your own infrastructure.

No. Applications sending over SMTP change host, port, and credentials only. API senders need a small client adapter, since Reloop is not a drop-in Mailgun proxy.
