To get started, make sure your SendGrid account is completely set up and your domain has been verified. The verification steps are outside of the scope of this tutorial, so we refer you to SendGrid's docs to get these steps done. Sending out emails without a verified domain is possible, but not recommended, as the chances of your emails being flagged as spam are very high.
The value for the mails per second field depends on your SendGrid account and settings. A good starting point is 5 mails per second.
If you are not there already, go to your Mailcoach Mail configuration page (under your user menu), make sure your driver is set to SendGrid, and choose a value for your Webhook signing secret. This should be an unguessable string, but don't use any passwords that you're already using. This secret will be used by Mailcoach to verify incoming events from SendGrid.
Also, copy the webhook URL that is mentioned on the same page and save your configuration.
Go to your SendGrid dashboard, open the Settings menu and go to your Mail Settings. Open and enable the Event Notification setting. In the HTTP POST URL field, paste the webhook URL that you just copied, and replace YOUR-WEBHOOK-SIGNING-SECRET by the webhook signing secret that you chose in the last step.
At the bottom, enable these actions to be reported back to Mailcoach: Dropped, Bounced, Opened, and Clicked. Finally, press the blue checkmark in the top right corner to save your configuration:
Your SendGrid configuration should now be complete, and you can go ahead and try sending a test mail. It may go to your spam if you have not set up your domain settings.
#Handling Sendgrid feedback in an existing Laravel app
You should only follow these instructions when you've installed Mailcoach in an existing app.
The spatie/laravel-mailcoach-sendgrid-feedback package can handle bounce feedback coming from Sendgrid. All e-mail address that permanently bounce will be unsubscribed from all lists.
At the webhooks settings screen at sendgrid you must add the Bounced, Opened, Clicked and Mark as Spam webhooks and point them to the route your configured. In the screenshot below we configured the webhooks using a ngrok.io domain with a ?secret=yolo-no-real-signature appended to the webhook url.
At the Tracking settings you must enable click and open tracking
In the mailcoach config file you must add this section.
// in config/mailcoach.php'sendgrid_feedback' => [
'signing_secret' => env('SENDGRID_SIGNING_SECRET'),
In your .env you must add a key SENDGRID_SIGNING_SECRET with the Sendgrid signing secret you defined when setting up the webhook.
Before start sending campaigns via Sendgrid we highly recommend getting in touch with their support and let them now the amount of mails your email list contains. Usually they will adjust the sending limits of your account so it's not a problem to send a large volumes in a short amount of time.
