Why You're Getting Emails from Close
Close has built-in email sequences that SDRs use for multi-step cold outreach campaigns with automated follow-ups. Unlike CRMs that rely on third-party integrations, Close includes native email sending, making it easy for sales reps to launch high-volume cold outreach directly from their pipeline.

How to Block Close Emails
Use Email Ferret
Email Ferret detects cold outreach from Close CRM sequences by analyzing sales intent signals, automated follow-up patterns, and BDR language. It identifies sequence-based outreach even when emails appear to come from individual senders.
Allowlist Trusted Close Senders
Close is popular with inside sales teams at startups and SMBs. If you have legitimate business contacts who use Close, add them to your Email Ferret allowlist so their messages are not flagged while cold outreach from strangers is still caught.
Create Gmail Filters as Backup
Set up Gmail filters targeting common cold email patterns such as sales phrases and meeting request language. This provides an additional layer of protection alongside Email Ferret for the most templated Close campaigns.
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 Close and other sales CRM with built-in calling and emails 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.
