Group emails by flow, feature, or type

When you are testing a complex application, your inbox quickly becomes a mix of password resets, welcome emails, order confirmations, and invoices. Collections let you sort these into separate groups so you can focus on one flow at a time.

Each collection has a name and a colour indicator that appears next to the email in the list. Assign any email from the collection picker in the email viewer. Filter the inbox to show only emails from a particular collection to compare variations or track changes across builds.

  • Name and colour-code each collection
  • Assign emails from the collection picker in the viewer
  • Filter inbox by collection
  • Collections persist across sessions
  • Move emails between collections at any time

Frequently asked questions

What are collections in LocalMail.dev?

Collections are named groups you can assign captured emails to. Each collection has a name and colour. You assign an email to a collection from the tags row in the email viewer. Collections appear as filter options in the inbox so you can view all emails of a particular type at once.

How do I assign an email to a collection?

Open any email in LocalMail.dev and find the Collection picker in the metadata row below the email headers. Click it to see a dropdown list of your existing collections. Select one to assign the email. You can move it to a different collection or remove it at any time.

Can I create my own collections?

Yes. Collections are created and managed in the LocalMail.dev settings. You can give each collection a name and choose a colour. Collections are stored locally and persist across sessions.
