How to Block Instantly.ai Emails
Create a Gmail Filter
Instantly rotates sender domains frequently, making domain-based filters less effective. You can filter by common sales phrases, but this risks catching legitimate emails.
Use Email Ferret
Email Ferret detects Instantly campaigns by analyzing behavioral patterns, sales intent, and automation fingerprints—even when sender domains rotate. This catches what Gmail filters cannot.
Report and Block
Block individual senders in Gmail and report as spam. While this helps with specific senders, Instantly's domain rotation means new emails will come from different addresses.
The Best Solution: Email Ferret
Gmail filters and manual blocking are reactive — they only work after you have already received unwanted emails. Email Ferret takes a proactive approach, automatically detecting cold outreach from Instantly.ai and other cold email automation platforms using heuristic analysis that looks for sales intent patterns, automation fingerprints, and BDR phrases. It works even when senders rotate domains or use AI personalization to disguise mass outreach.
