How to connect a Google Workspace account to MailReach with Less Secure Apps

Important to know

Less Secure Apps are no longer supported for accounts, they're still supported for Google Workspace but will be phased out at a later date. This date is not announced yet.
For this reason, we recommend to connect your Google Workspace account to MailReach with an App Password.

Step 1 : Turn on Less Secure Apps on the Google account you want to connect to MailReach

Sign in to the Google account you want to warm.
Once signed in, go to
Very important, make sure you're on the right Gmail account by clicking on the avatar on the top right. Otherwise it will turn on Less Secure Apps on the wrong Gmail account.
Turn on Less Secure Apps by clicking on the selector.
At that time, Google often triggers security alerts and can block the process. Go in the inbox and check if you have received 'security alert' emails from Google. If yes, open them all and reassure Google by answering "It was me".

Step 2 : Enable IMAP in the Gmail / G Workspace account

In the mailbox, go to the Settings by clicking on the wheel on the top right like in the screenshot below (1)

Then go to the Forwarding and POP/IMAP settings (2).
Click on enable IMAP (3).
Save (4).

The settings should look like this:

Step 3 : Go back on MailReach and sign in

Go back to MailReach.
Sign in.

If you can't manage to connect, no worries, we got your back. See the section below.


Scenario 1 : I can't enable Less Secure Apps

First, if you have Two-Step Verification (2FA) enabled on this account, you can't allow Less Secure Apps.

In that case, you need to turn off Two-Step Verification :

Click on the Avatar in the top right corner and then click on Manage your Google account.
In the navigation panel, select Security. Scroll down a bit, under Signing in to Google, click on 2-Step Verification
Disable it.
Go back to Step 1.

If you don't have Two-Step Verification and still can't enable Less Secure Apps, it means that on the Admin level of the Google Workspace, this option has been deactivated.

The Admin needs to allow the users to turn on the Less Secure Apps.

To do so :

You (if you have an Admin account) or the Admin, needs to sign in to Google as an Administrator of the Workspace.
Once signed in as an Admin, go to
Select Allow users to manage their access to less secure apps
Go back to Step 1 to allow less secure apps.

Scenario 2 : I've well enabled Less Secure Apps but still can't connect to MailReach

Google may have triggered security alerts and blocked the process.

Go into the inbox of the Gmail account.
Check if you have received 'security alerts' emails from Google. If yes, open them all and reassure Google by answering "It was me".
Go back to the Step 1, check if Less Secure Apps have been turned off by Google and turn them ON again.
Check if you received again new security alerts. If yes, open them and answer "It was me".
Go back on MailReach and try connecting the account again.

Use the Display Unlock Captcha

Open a new navigator window in Incognito Mode.
Sign in to the Google account you want to warm on MailReach.
Once signed in, go on (in the incognito mode window).
Click on continue.
Go back on MailReach and try connecting the account again.

Make sure you're entering the right credentials

I know it seems obvious but it happens to the best of us.

Make sure to enter the right email address and password when connecting the Google account to MailReach.

Make sure you didn't do all the steps for another Gmail account (usually happens when you're signed in on several Gmail accounts at the same time)

This case is common. Make sure that :

You've properly enabled Less Secure Apps for the correct Google account.
If you received alert emails from Google, replied "It was me".
Enabled IMAP on the correct Google account.
You've put the right credentials when trying to connect the Google account on MailReach.

If, after trying all that, you still can't connect, please send us a message using the chat, we'll do our best to help 😇
