To connect and warm a SendGrid email to MailReach :

* You have to connect the SendGrid SMTP (Step2) by entering your SendGrid API key.
* AND you need to connect an inbox (= IMAP / Step3) where you'll receive the replies of the email warming activity. This inbox (IMAP) is where you receive the replies of your SendGrid emails.
* If you have all the information : it should take 3 minutes.

# Step 1 : On MailReach, fill in the first fields

Email address to warm : you get it, your SendGrid sending address

# Step 3 : Enter your IMAP credentials (the inbox where the replies of your SendGrid emails land)

|| MailReach needs you to connect an inbox (= IMAP) to generate meaningful conversations, put the replies in threads and hide MailReach emails from your inbox. 
Your IMAP information are the credentials of **the inbox where the replies from your recipients land**. 

For example, if you send email campaigns using SendGrid, on which inbox do you receive the replies from your recipients to your SendGrid address?

If that's a Gmail, you'd need to enter the details of this Gmail inbox in the IMAP fields. Same for Outlook / Office 365. It could be another, it depends on what you prefer using.

### 1. If you don't have yet any inbox to receive the replies of your recipients : you can create a Google or Office 365 inbox and use it to connect with IMAP. We recommend Gmail as it's easier to set up.

### 2. In all cases, you have to **adjust the settings of the mailbox to be able to connect it as IMAP to MailReach** :

* For a Gmail / Google Workspace inbox, you need to **create an App Password**. To do so, please **follow the first 3 steps of this guide** : [Connect a Gmail / Google Workspace to MailReach with an App Password](/en/article/how-to-connect-a-gmail-google-workspace-account-to-mailreach-with-an-app-password-ulwj00/)
* For an Office 365 account, use the settings here : [Office 365 settings](/en/article/how-to-connect-an-office-365-account-to-mailreach-1jya3ru/)
* For any other IMAP / inbox type : it depends of your inbox provider. You need to check directly with them to get the IMAP credentials needed.

### 3. Go back to MailReach. Enter the information as following for IMAP :

For a Gmail / Google Workspace inbox : 
* IMAP host : imap.gmail.com
* Port : 993
* IMAP username : your **Gmail inbox address**
* IMAP password : the **App Password** generated for MailReach (in the previous section). **NOT the password of the Gmail account**. 

For a Outlook / Office 365 inbox : 
* IMAP host : imap-mail.outlook.com
* Port : 993
* IMAP username : your Outlook address
* IMAP password : your Outlook password

For any other IMAP / inbox type :
* Get the details from your inbox provider.

# Step 3 : On MailReach, fill in the connection form and sign in
