Message Storage

When you have an account and make an email address private, message storage kicks in.

Message storage comes into play in two ways. It governs:

  • The number of messages allowed across your owned email addresses
  • The number of starred messages

When are Messages Recycled?

The oldest, unstarred messages are removed.


If your storage limit is 100 messages, and you star 25 messages, and you own 3 email addresses, you’ll be allowed 75 messages across those 3 email addresses.

Once you have 100 messages across all your starred and private email addresses, the oldest unstarred ones will be removed.

Getting More Storage

Message storage can be purchased on a per-message basis in blocks listed on the pricing page.

Starred (saved) Messages

Mailsac will delete messages on regular intervals. One way around this is to create an account and star messages so they will be saved.

Use the star symbol ★

When you star a message, it counts towards your overall storage. But once it’s starred, you can be sure it will not get recycled, so you can refer back to it later.

Your user dashboard has links to all inboxes where you starred messages.

You can star messages on any address, including those you own or other public addresses.
