How to use SendGrid's SMTP with Quickmail

Setting up QuickMail to send emails via SendGrid means emails will be sent out from SendGrid's SMTP service instead of the email account's default sending service. 

Following these steps will ensure better deliverability and will keep the email reputation safe from risks brought by sending to bounced emails. 

Set up SendGrid as a custom SMTP in Quickmail: 

Go to Settings > Inboxes and click on your Inbox.
Find the custom SMTP fields and fill out with the SendGrid credentials:

Address: smtp.sendgrid.net
Example SendGrid credentials:

SMTP Address: smtp.sendgrid.net 

Port: 587 

SMTP Login: should be your login account to SendGrid 

SMTP Password: should be your password to your account

Whitelabeling your domain

Authenticating the emails sent out from SendGrid will help with email deliverability. 
Setting up SPF and DKIM records in the domain's control panel will improve email deliverability and will remove the "via SendGrid" text in the emails sent out from SendGrid's SMTP.

Forwarding Bounced Emails from SendGrid

By default, SendGrid does not send bounce reports to the inbox of the address that emails are sent from. 
That means follow-ups may get sent to bounced prospects (which is not ideal). 
For that reason, bounce forwarding needs to be set up in SendGrid so that Quickmail can detect the bounces and stop the follow-ups on bounced prospects. 
While logged in to the SendGrid account, go to Settings > Mail Settings > Enable Forward Bounce > click the check mark to confirm.
