Cold outreach thatyou actually own
Describe the outreach you want. It builds the founder list, writes the copy from your resume, and hands you a campaign to review — sent through your own Hostinger mailbox. No middleman, no per-email fees, no lock-in.
Workflow
Four steps to your first campaign
Connect a sender
Add a Hostinger Mail API token for a mailbox you own. Sender secrets are AES-encrypted before being saved.
Add your resume
Upload a PDF once. It is read into a profile every generated email is written from, and you can correct anything it misread.
Describe the outreach
Ask for what you want and the assistant searches founders, builds the list, and drafts the campaign. Or do each step by hand.
Review and launch
Check the recipients, the sender, and the credit cost, then launch. Sends throttle themselves from there.
Assistant
Describe it. Review it. Send it.
Say what you want in plain English. The assistant searches the founder database, builds the list, writes the copy from your resume, and leaves a draft campaign for you to check — nothing goes out until you say so.
- Two modes
- Review prepares everything and stops at a draft you launch yourself. Auto sends what you asked it to send, one campaign per message.
- Grounded in your resume
- It reads your profile before writing, so the copy cites work you have actually done instead of generic filler.
- Shows its work
- Every search, list, and draft appears in the transcript with real numbers, so you can see what it did before you commit.
Features
Everything you need. Nothing you do not.
OutreachMailer is purpose-built for founder outreach. It is not a bloated CRM or an expensive sending platform, just the tools required to search, write, send, and inspect.
Plain English
Outreach assistant
Ask for ten W25 founders or a shorter template, and it searches, builds the list, and drafts the campaign for you to review.
PDF in, profile out
Resume-aware copy
Upload your resume once. Templates and variation sets are written from your real projects and skills, then land in the editor for you to approve.

Open source
Credential handling
Hostinger API tokens are encrypted before database storage.
Credit system
300 emails per day. Per sender account.
Credits are tied to your sender account, not just your login. Each sender receives 300 credits per 24-hour cycle. Each founder email or test email uses 1 credit, and the full campaign cost is charged at launch.
- 1 credit per email
- Each founder email and each optional test email costs 1 credit.
- Charged at launch
- The full campaign cost is deducted when the campaign launches.
- Sender-safe throttling
- Emails are spaced apart per sender to avoid bulk-send spikes.
Security
Your credentials, locked tight.
OutreachMailer encrypts Hostinger Mail API tokens before storage. It is open source, so you can audit the path yourself.
- AES encryption at rest
- Hostinger API tokens are encrypted before being written to MongoDB.
- Sending stays yours
- In review mode the assistant has no send tool at all. It prepares the draft; you press launch.
- Provider-owned access
- Access is an encrypted Hostinger Mail API token you can revoke at any time.
- No shared infrastructure
- Every send uses your sender account, not a shared mail pool.
