Detect and block email tracking attempts

Nowadays, a growing number of services tracks your email activity without your consent, making possible for your contacts to know when, where and how many times you have read a message. Since 2013, Gmelius protects your privacy by detecting and blocking such trackers in Gmail, providing a detection algorithm which has been since copied but never outsmarted !

Detect and block trackers

Compose emails on the fly

Gmelius introduces the ease and power of #hashtags to your inbox! Insert pre-saved email templates, add senders and categorize new emails and replies just by appending hashtags to the subject of your messages.

Search your inbox from any tab

Gmelius lets you search for messages in the address bar of your browser, just like you would perform a normal Google search. To initiate a search, type gml in the address bar followed by your query, e.g., gml from: [email protected]

info_outlineThis feature is currently only supported in Google Chrome.

Unsubscribe from newsletters and mailing lists in Gmail

Unsubscribe from newsletters

A new Unsubscribe button replaces the Spam one whenever Gmelius detects an email newsletter or a mailing list, making the whole unsubscription process swift and easy.

info_outlineIs this a duplicate of Gmail's own Unsubscribe feature? No, Google only looks for the "List-Unsubscribe" header, present in a very small number of newsletters, while Gmelius approach is more complete and leads to a significantly higher level of detection.

Make Gmail header visible on-demand

Make the Gmail header, that is the logo and search block, auto-expandable on demand and prioritize so the content of your inbox. If you enable this feature, Gmelius will add a new search button at the top-left of your inbox that will display/hide the header and auto-focus the search input. This feature includes a keyboard shortcut.

Automatically Cc or Bcc your emails

Gmelius can automatically Cc or Bcc your emails to recipients of your choice according to the address present in the "from" and "to" fields.

Return read receipts in Gmail

Return read receipts

Tired of people sending you emails to know if you have received and read their previous emails? Gmelius adds a receipt button to your favorite inbox - click on it and an email will be automatically sent to confirm the good reception of any new message.

Send and label

Gmelius helps you quickly categorize emails you're sending out with a label of your choice. Enable the feature in your Gmelius settings, and click the newly created button whenever you wish to send a message and classify it.

Save clicks, save time, stay organized.
