Frequently asked questions

How often should I verify my newsletter list?
Verify new signups in real time and clean the full list before major sends, plus before any re-engagement campaign since old segments decay the fastest.
Does verification help with spam traps?
Verification removes invalid and many risky addresses that correlate with traps, which lowers the chance of the listings that damage sender reputation.
