All features
A/B testing
Split subjects and body copy 50/50 across recipients and compare what actually converts.
Every campaign can run two variants in parallel. SpringMail tracks send, bounce, and reply signals per variant so you can double down on winners instead of guessing from gut feel.
What you get
- 50/50 split on subject lines and body copy
- Per-variant send, bounce, and reply rates
- Reply tracking from mailbox ingest (not opens)
- No extra setup — enable when you create a campaign
