   This is required.

3. Enter IP Pool

   This is not required. Enter this if you purchased an IP at SparkPost. Purchasing an IP is recomended and will ensure better open rates.

4. Enter Verified Domain

   This is required. This is the domain you verified that you can send from. If some of your from addresses are do not share the same domain name, you can still send using them, but the "From" address will need to use the verified domain. The 'reply to' address can be anything.

5. Enter Fallback From Address

   This is required. This is a From address that will be used if your 'reply-to' address is not from your verified domain.

6. Select as Default ESP

   A default ESP is required. If you have multiple ESPs entered, then you must choose one of them as your default.

7. Click "Update SparkPost Settings"

   This saves the information.

8. Click "Confirm Credentials"

   This will tell you if you can connect to SparkPost. If this fails, it can only mean that your secret is incorrect. It does not confirm your Bounce and Complaint settings are correct. They are verified at SparkPost.
