// migration
From Mailgun to VoltMail in an afternoon.
Most teams cut over in a single sprint. The four-step playbook below works at any volume — from 10k a month to 10M.
- 1
Export your suppression list
Mailgun provides a CSV export. Drop it into our importer — 1M rows in under 90 seconds.
- 2
Verify your domain
Paste the domain; we generate SPF, two DKIM selectors, DMARC, and BIMI records. Verification ≤ 90s.
- 3
Swap the SDK
API surface is near-identical. Most apps need a 30-line diff. We publish a codemod for the common cases.
- 4
Cut over with idempotency
During migration, send via both providers using the same Idempotency-Key. We dedupe, you double-check, then flip DNS.
“Mailgun's inbound parsing was good. VoltMail's is good plus typed plus replay-able plus included.
