Create hyper-personalized cold emails at scale

HeyStranger pulls fresh leads from Apollo, verifies every email, reads each prospect's website & social media, then uses the information to create any personalization you can think of. Mention direct competitors, ideal customers, their value proposition, PS compliments, warm introductions, and more. The result is a CSV that's ready to drop into any outreach tool—no manual research, no generic, robotic mail-merge.

Merge tags swap in static data ( {{firstName}} , {{company}} ). Our AI writes individually unique phrases and sentences for each prospect after digesting their site or social media. It references real details—recent blog posts, product features, fund-raises, and more—so the email reads as if you wrote it by hand.

No. A free Apollo account is enough to build a People search and copy the URL. HeyStranger does the heavy lifting and returns the contacts under your credit balance.

Every address passes through MillionVerifier in real time. We hit 97%+ deliverability across millions of sends, so bounces stay low and your domain reputation safe.

One credit equals one contact—simple. If you scrape 1,000 leads you spend 1,000 credits, with no hidden multipliers for enrichment or verification.

No. We only process publicly available data while you control compliance settings in your sending platform.

Small lists finish in under a minute. Bigger scrapes run in the background—you'll see live status updates and get an email when your list is ready to export or personalize.
