1. Boomerang

Boomerang allows you to schedule your emails to be sent at a particular time. It is a great tool for busy people who like to plan ahead of their schedule. For example, if you have an email that need to be sent on Monday morning 6am, you can write the email on Friday night (just before you leave for the weekend) and schedule it with Boomerang to deliver on Monday morning.

2. CloudMagic

CloudMagic is a search extension that can search your mails faster than Gmail itself. On top of that, it allows you to preview and interact with the search results without requiring you to leave your current mail. While composing a mail, you can search for a file (with CloudMagic) in your Google docs and drag the documents from the preview window to the mail to attach it as an attachment. Of all the Gmail apps I have seen, this has to be the coolest.

3. OtherInbox

OtherInbox is an organizer for your Gmail account. Once installed, it will scan your Gmail inbox and sort your emails to various categories (via label). It also has an “unsubscribe” category where all mails placed in it will be automatically unsubscribed. Even if the unsubscribe link does not work, you can be sure that emails from this sender will not appear in your inbox again.

4. Find Big Mail

Find Big Mail helps you to identify the big mails that are taking up tons of storage space. It scans your inbox and sort the emails with file attachments into various folders. Attachment with file size less than 500KB are labelled as “My Big Mail” while bigger than 2MB are labelled as “My Ultra Big Mail”. You can then switch to those folders and delete those big emails to free up storage space.

5. ActiveInbox

ActiveInbox allows you to project manage right within your inbox. You can turn emails into prioritized tasks, set deadline for projects and set reminder for to-do list.

6. Taskforce

Taskforce is a simple app that allows you to convert your emails into tasks and manage them right within your Gmail.

7. AwayFind

AwayFind is an interesting app aimed to bring you away from your inbox without missing the important mails. Instead of checking your inbox all the time, when you receive an urgent message, AwayFind will notify you via your mobile device, a voice call, IM, or even delegate the message to someone you specify.

8. Greplin

Greplin allows you to search your emails without having to login to your Gmail. Other than Gmail, it also supports Google Docs, LinkedIn, Facebook, Twitter, Dropbox, Evernote and many more applications. All you need to do is to link up all your accounts with Greplin and you will be able to search them all in one place.

9. SaneBox

SaneBox is functionally similar to OtherInbox, except that it is more aggressive in its approach to achieve zero inbox. It scans your inbox and leaves only the important emails in your inbox. The rest are then sent to the @SaneLater folder where you can read it when you are free. If you have a whole bunch of unread emails, it can instantly reduce that number by half.

10. Emailga.me

Do you need more motivation to clear your emails? The developers at Baydin (the same developers behind Boomerang) created a game for Gmail where you can play while clearing your email. The rule is simple. Clear your emails and you will receive points. The faster you clear, the higher point you will receive. The higher points you have, the higher is your ranking in the leaderboard.

11. Rapportive

Rapportive takes the sender’s email address and performs a search on various social networks. It then displays the sender’s info on the sidebar (the place where Google Ads are shown) so you know who you are dealing with.
