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

01

Connect a sender

Add a Hostinger Mail API token for a mailbox you own. Sender secrets are AES-encrypted before being saved.

02

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.

03

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.

04

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.

300 emails / day

Verified founder emails

Reach each selected founder through the verified email stored in your database, with predictable credit usage and no extra sending fees.

Tiptap-powered

Rich campaign editor

Write formatted emails with links, lists, emphasis, and dynamic insertion tokens.

No shared pool

Your sender, always

Send through your own Hostinger mailbox so replies land in your inbox and reputation stays yours.

Search + filter

Prospect lists

Group founders into reusable audiences and send multiple campaigns to the same list.

Full audit trail

Send logs

Inspect every success, provider error, retry state, and campaign event from one clean history view.

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.
