email.casla.app

Built for small outreach teams

Outreach that goes out one email at a time, from your own inbox.

Bring your list, write one message, and email.casla.app delivers it from your connected Gmail or Microsoft account with a natural gap between each send — inside your working hours, up to your daily limit, and never on the days you switch off.

Your own inbox

Connect Gmail or Microsoft once. Every email is sent from your real address, so replies land where they always have.

Naturally spaced

A random gap between each send, a start and end time, chosen weekdays and a daily cap you control.

Shared mailboxes

Invite colleagues into a workspace and send on behalf of any connected mailbox — no password sharing.

How a activation works

  1. 01

    Add your people

    Upload a spreadsheet, paste a list, or let the assistant tidy it up.

  2. 02

    Write the message

    Use {{FirstName}} and {{Company}}, add images or GIFs, and your signature.

  3. 03

    Check the queue

    Every email is shown as its own row so you can edit before it goes.

  4. 04

    Press send

    Emails leave one by one, quietly, across your working day.
