Bulk create mailboxes on your Mailcow server from a spreadsheet

Reads a CSV of employee details and creates each mailbox and email alias on your mail server automatically.

How the work actually flows

It repeats. Repeats process next row.

Mailcow

The problem it solves

Setting up email for a new batch of employees means creating each mailbox and alias by hand, one at a time. When you're onboarding several people at once, that's a lot of repetitive setup work that's easy to get wrong or fall behind on.

Who it fits

IT admins who manage their own mail server and regularly onboard new employees or accounts.

How it works

You submit a spreadsheet with each person's name, address, password, and any aliases
The system reads through the list one row at a time
Each mailbox is created on your mail server with the details provided
Any listed aliases are added to that mailbox

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.
