Checked. Now see who reads what you send.
A clean setup gets your email delivered. Outsolvi covers what happens next: every open graded as a person or a machine, who clicked and who replied, and follow-ups that stop when someone answers. From $7/user/mo billed yearly, 14-day free trial.
Start free trialChecks the domain against a built-in list of the most common disposable email providers, and separately flags role-based local parts like info@ and support@. The list covers well-known throwaway domains rather than the full public registry, so read a clean result as "not a known disposable" rather than proof the address is real.
On signup forms (block or flag). When cleaning prospect lists imported from public sources.

Depends on the funnel. For paid: block. For free / freemium: flag but allow; some legitimate users use them for privacy.
