What Are Mailboxes?

Last updated: May 21, 2025

Article Overview:
This guide explains what mailboxes are, why they’re essential for your outreach campaigns, and how using multiple mailboxes can improve deliverability.


What are mailboxes?

In Artisan, mailboxes are subscription-based email accounts connected to your instance. They’re used to send cold outreach emails and receive replies from engaged leads.

Once you’re fully onboarded, we’ll provide mailboxes based on your monthly lead volume. These are fully managed by our team and you’ll only need to confirm you're happy with the domain names we've selected.

Note: While you can use your own mailboxes, we strongly discourage it. Self-managed mailboxes typically have poor deliverability compared to ours, which are warmed up and optimized for outbound.


Why do I need mailboxes?

Without mailboxes, Ava can’t send emails - which means no outreach.
Each sender in your account is assigned their own mailbox to ensure clean separation and avoid one overloaded inbox for everyone.


Why do I need multiple mailboxes?

The number of mailboxes you receive depends on your monthly lead volume. The more leads you plan to contact, the more mailboxes you’ll be assigned.

This setup improves deliverability by:

  • Distributing outreach across multiple domains

  • Reducing the risk of being flagged as spam

  • Keeping sending volumes lower per mailbox


Mailbox warmup period

All Artisan-provided mailboxes go through a 14-day warmup period before they can be used. Once the warmup is complete, they’ll be automatically connected to your account.
