best free tools I use to get a 70% reply rate from cold outreach
read the article first, then steal this stack:
1. finding the right person
@boardyai. tell it what you’re building and it’ll find someone relevant from 240k+ people it has talked to. if you can get a warm intro, take it
@TheOrgCom. free org charts with reporting lines, titles, and team sizes. really useful when you know the company but have no idea who you should actually message
2. searching X
X advanced search. completely free and still insanely underused. use operators like min_faves:500, since: and from: to find people already talking about the problem you solve. also great for researching someone before reaching out
3. finding contacts
@useapolloio. 900 credits a year, granted monthly
@prospeo_io. 100 credits a month. searches are free, you only use a credit when you reveal a contact
both are enough if you’re doing targeted outreach instead of blasting thousands of people
4. finding the email
@EmailHunter. 50 credits a month. domain search helps find the company’s email pattern, then you can verify the address before sending anything
5. making sure your emails actually land
CanISendThis by
@jessethanley. send it an email and it checks SPF, DKIM, DMARC, unsubscribe headers, and deliverability across Google, Yahoo, and Outlook. takes around 30 seconds and can save you from wondering why nobody is replying when your emails are just going to spam
6. researching the person
@clay. 500 actions a month. Claygent can research someone across the web and pull together the useful context
F5Bot. free alerts whenever someone or something you’re tracking gets mentioned on Reddit or Hacker News
Google News RSS. add /rss to a Google News search and you’ve got a free live feed for that person or company. fundraises, launches, new hires, interviews. basically all the context that can give you a natural reason to reach out
7. finding where they’ll actually reply
@whatsmynameproj. put in one username and it checks 700+ platforms. people reuse usernames everywhere.
sometimes finding someone’s X, Telegram, or another personal account is much more useful than sending another. email to an inbox with 500 unread messages
8. writing the message
no tool. seriously. use AI for research. use it to critique your draft. use it to find things you missed
but write the final message yourself. people are getting very good at recognizing AI outreach
the tools can find the right person and give you all the context. you still need to think
