Everything a sender needs, nothing they don't

Six tools that replace a stack of spreadsheets, scripts and guesswork.

Sending that paces itself

Delays with jitter, batch sizes and rotation across as many sending accounts as you like — or use the built-in mail server with zero setup.

Clean lists before you send

Catch duplicates, disposable domains, role addresses and typos, then export the cleaned list in one click.

Know exactly what happened

Real open rates, click-throughs, bounces and per-recipient logs for every campaign you run.

Spam score before you hit send

Live scoring highlights risky words in your subject and body and tells you what to rewrite.

A pool of sending accounts

Add Gmail, Outlook, Zoho, iCloud or any custom mail server, test each one, and spread sends evenly.

Pause, resume, never lose work

Your subject, body and recipient list stay put while you move around the workspace.

More about SOJMAILER

SOJMAILER started as a workaround. We were sending author newsletters through a patchwork of scripts, three mail accounts and a spreadsheet of addresses that nobody trusted. Delivery was a coin flip and nobody could say why a send failed.

So we built the tool we wanted: one workspace where the list is cleaned, the copy is scored, the sending is paced across every account you own, and every recipient has a log entry you can point at. No enterprise contracts, no per-seat maths, no card on file — just a send button that behaves.

Your credentials stay on your device, never in a shared inbox
Built-in sender domain so you can send on day one
Open, click and bounce tracking on by default
Works for 200 recipients or 200,000

STEP 1

Clean the list

Paste or upload, strip duplicates and dead addresses.

STEP 2

Write and score

Compose, preview, and fix whatever the spam scorer flags.

STEP 3

Pick your senders

Built-in server or your own accounts, rotated evenly.

STEP 4

Send and watch

Live progress, pause any time, real results after.

What senders tell us

We went from a spreadsheet and a lot of guessing to 40,000 clean sends a month. Open rates doubled because the list cleaner threw out the junk first.

Founder, Storyroom Books

The pacing controls are the whole reason our domain still has a good reputation. Nothing else gave me jitter and rotation in one place.

Daniel Reyes

Growth lead, Northsail

I run nine client lists from one workspace and the per-campaign logs settle every 'did it send?' question in seconds.

Fatima Bello

Agency owner, Bellow Media

Was sending in ten minutes, no sales call. The built-in mail server just worked.

Indie maker

Questions

Do I need my own mail server?

No. The built-in mail server sends for you out of the box. You can also add your own Gmail, Outlook, Zoho or custom accounts and rotate between them.

Will my emails land in the inbox?

That depends on your list and your copy, which is why the spam scorer and list cleaner run before you send, and why pacing is on by default.
