Outreach that writes like you
Postlet finds the right people, writes every email and LinkedIn message in your own voice, sends from your Gmail at a safe pace, and learns from every reply what works. You only answer the replies.

Question opener vs. straight to why them
How it works
One conversation to set up. Then it runs.
Setup is a short chat. After that, agents source, write, send and learn on their own, and you see every decision.
Who should we reach first?
Tell it
Describe your company and who buys
Postlet reads your website, proposes the audiences worth testing and the roles to reach at each company. You keep or skip each one.
Connect
Connect Gmail, and LinkedIn if you like
It reads your sent mail to learn how you write, checks your domain is set up to send, and paces each mailbox to what it can safely carry.
Learned this week
Asking for advice gets twice the replies of a product pitch from VPs at fintechs.

It sends, tests and improves
Every sequence is written for one person. Something is always under test, and what wins becomes how every email is written. Replies come to you.
Why Postlet
An outbound team, without the template
In your voice
Learned from your own emails and LinkedIn messages, and from every edit you make. A reader checks each draft for words you would never write.
Experiments, not guesses
Openers, angles, asks and timing are tested on real replies. A change is adopted only when the evidence supports it, and a holdout checks it stays right.
Safe sending
Warmup, daily limits, recipient-local hours and bounce brakes, enforced in code. Nothing sends without SPF and DMARC.
Never the wrong company
Competitors, your customers and anyone you rule out are on a do-not-contact list checked at every step, before anything is paid for or sent.
LinkedIn, optional
Connection requests a few days before the first email, and a short message after someone accepts, in your LinkedIn voice, within LinkedIn’s limits.
You stay in charge
Pause at any time, edit any unsent email, and change anything by asking. The agent never answers a reply. You do.

What Postlet does with your Google account
Postlet asks for two Gmail permissions, and uses them only to run outreach you set up.
Send email gmail.send
Sends the emails in your sequences from your own Gmail address, at the pace you agreed.
Read email gmail.readonly
Notices when someone replies so their sequence stops at once, and reads your sent mail to learn how you write.
- Never sold, never used for advertising, never used to train general AI models.
- Nobody at Postlet reads your mail, except with your permission or where security or the law requires it.
- Access tokens are encrypted at rest, and every workspace is isolated from every other.
- Disconnect at any time from Settings, or from your Google account. You can ask us to delete your data.
