In this guide we’ll walk through having an alternative email sending setup through Amplemarket’s SendGrid infrastructure (using SMTP):

  1. Setup your account in SendGrid
  2. Authenticate your Domains
  3. Link your SendGrid account to your Amplemarket’s Mailboxes

1) Setup your account in Sendgrid

  • After Amplemarket provides your credentials to access your SendGrid account, you'll need to make your first login into Sendgrid - https://login.sendgrid.com/login/password
  • Setup a 2FA authentication, and then you'll be able to log in.

2) Authenticate your Domains

This step will allow us to send emails through our SendGrid infrastructure but they still show up in the recipients mailbox as though they came directly from you.

If you want to send emails from a mailbox using Amplemarket's SendGrid as your custom SMTP, you must first make sure you’ve completed this step for the domain of that mailbox.

You’ll have to repeat this step independently for each domain, in general the steps boil down to:

  1. Pick a domain

    1. If your domain is hosted in GoDaddy, you’ll be able to perform an automated setup, otherwise it will be manual.

  2. Insert the domain into SendGrid



  3. SendGrid generates several DNS records

  4. Go into your DNS provider to add these records for the domain you’ve chosen

  5. Go back to SendGrid and press the verify button to validate setup was done correctly

You can find the specific step-by-step guide in SendGrid’s documentation:

 

3) Enable Bounce Detection

This will allow Amplemarket to continue to detect bounced emails.

  • Go to Mail settings > Event Settings
  • Enable “Forward Bounce Messages”

4) Link your Amplemarket’s Mailboxes to your SendGrid account

In this step we’ll finally enable your Mailboxes to send email using Amplemarket's SendGrid as your custom SMTP.

The first step is to generate a SendGrid API Key.

You can generate one API Key and use it for all your mailboxes:

  1. Go to Settings > API Keys > Create API Key.
  2. On the API Key Name, put the identification for this API Key, could be anything (e.g amplemarket-smtp)
  3. Select “Full Access”, and click “Create & View”
  4. Copy and save this API Key; you won't be able to see it again! ⚠️

Now that you have an API Key, you can connect a Mailbox to SendGrid, you must repeat this step for each mailbox you want to connect:

  1. Go to Amplemarket > Settings > Mailboxes > click on the “…” in the mailbox that you want to use the SendGrid SMTP

  2. Click on : Configure custom SMTP

  3. Fill out the SMTP settings form:

    • SMTP Username: apikey
    • SMTP Password: the API Key that you generate in the last step
    • SMTP Host: smtp.sendgrid.net
    • SMTP Port: 465
    • SSL Required: checked

    Click on “Connect & Enable”, and it should succeed.

    The mailbox is now connected and ready to outbound.
