Sieve catches what spam filters on Gmail miss. Customize its filter to get rid of sales pitches, broker inbound, recruiter blasts, and anything else you don't want to see. Real mail from your network or cold outreach you actually care about is untouched. It's also built to protect you from phishing attacks. Built with privacy in mind. Sieve never stores your email content and is CASA Tier 2 certified/SOC2 in-progress. It never deletes anything and your corrections teach future classification.

Hey PH ! 👋 I'm Kevin, one of the creators of Sieve. We built Sieve out of personal frustration. Gmail's spam filter is great at catching obvious junk, but the mail that actually eats your day sails right through it: cold sales pitches, recruiter blasts, broker inbound, "just bumping this to the top of your inbox." It lands in your Primary tab looking like real mail, and you have to read each one to know it isn't. Sieve sits on your Gmail and classifies every incoming email. Cold outreach and phishing get labeled and archived before you see them. Real mail from your network and anything you signed up for is left alone. A few things we sweated over: 🔍 You see it work before you trust it. When you connect, Sieve scans your recent inbox and shows you exactly what it would have filtered, with real examples from your own mail. ↩️ Nothing is deleted. Everything Sieve filters stays in your Gmail under a label. Pull one back to your inbox and Sieve trusts that sender from then on. Drag a pitch into the label and it filters that sender going forward. Your normal Gmail habits are the training. 🔒 Privacy first. Sieve never stores your email content and passed Google's CASA Tier 2 security assessment for Gmail access. SOC 2 is also in progress. There's a free trial, so you can watch it clean your inbox for a week before paying anything.

Finally a filter that actually catches the recruiter spam my Gmail rules keep missing. Love that it doesn't touch the cold outreach I want to see and the fact that nothing gets deleted.
