Why re-verify an email list?
Nobody remembers
Re-checking by hand is the job that never gets done.
Your tool never hears
Even when you find bad addresses, updating the email tool is manual.

How do monitors work?
Connect your tool
Link Mailchimp, Brevo, MailerLite, GetResponse, ConvertKit, HubSpot or AWeber.

Daily to yearly, at a time you choose, for new addresses or the whole list.
It runs itself
Each run creates a verification job you can open, filter and export.
Write back if you like
Tag or unsubscribe the verdicts you choose in the source tool.
