Before any of your outreach copy matters, you need the right person's actual email, and Hunter is the most widely used, straightforward way to find and verify it. Its Domain Search helps you figure out who to contact at a company, the Email Finder gets you the address, and the verifier keeps you from bouncing and wrecking your sender reputation. The free plan is enough to get a founder started without a card.
When you have a name and a company but no address, Hunter is the default first stop: type the person and the domain, and it returns the verified email or its best guess with a confidence score. The free tier gives you 50 searches a month with no card, which is plenty when you are reaching out one founder at a time rather than blasting a list. It works off publicly available data and shows its sources, so you are not scraping anyone manually.
Hunter built its business around helping people find and email the right person, so this guide doubles as both a practical how-to and a free tool you can actually use to find verified addresses and track opens. It's a solid one-stop reference to come back to once you're ready to send, not just read about it.
A free five-day email course covering the whole cold email process end to end: defining who to target, finding accurate contact details, writing the message, and following up. Good if you want a structured path instead of piecing advice together from a dozen separate articles.
A large, organized reference bank when you want more raw examples to riff on than the individual essays above give you. It is explicit about what kills a subject line, overused phrases like 'Quick question' that now read as templated, which matters directly for the rule of skipping anything auto-generated.
Written by a company that sells a cold email tool, so it is pragmatic rather than legalistic: what to put in your first email so it is compliant (who you are, why you are writing, where you found their address, how to opt out) and where legitimate interest actually breaks down. Good sanity check before your first EU-facing send.
Plain-language breakdown of every cold email metric (open, reply, positive reply, bounce) and what actually separates a healthy campaign from a broken one. Written by a tool that sends and tracks huge volumes of cold email, so the numbers are grounded in real send data, not guesswork. Good first stop for defining what you should even be measuring before you start diagnosing your own numbers.
A short, practical checklist for raising reply rates once you already know your baseline is low. It walks through list size, sender domain, and personalization in roughly the order they actually matter, which mirrors how you should triage your own broken campaign. Read it right after the metrics page above to move from diagnosis to fixes.
