To leverage from SparkPost functionality and features, you may want to connect to Folderly for maintenance procedures.
The connection process will consist of two steps: SMTP credentials creation in the SparkPost web app and mailbox connection with Folderly.
First, you need to create SMTP Password which is a specific API-key for your SparkPost sender account.
From your SparkPost dashboard go to Configuration section -> API Keys (1-2). Then, click the [Create API Key] button (3).
Here, you can customize a new API Key:
(4) give it a meaningful name (used only within the SparkPost API keys list);
(5) customize API permissions;
(6) make sure to select the 'Send via SMTP' permission.
Click the [Create API Key] button (7) to save API key. You will be redirected back to the API keys list and an announcement with your new created API key will pop-up. Make sure to copy and save this key, we will need it to connect with Folderly.
Now, go to your Folderly user cabinet. To connect a domain with Folderly, on the home page click the [Add mailbox] button. Select "SPARKPOST" and click [Next step].
Enter the API Key you created within SparkPost in the "SMTP password" field.
The last step of the setup is to configure the mailbox. Fill-in the fields:
"Email address" — Mailgun Sender Email, used for marketing campaigns;
"Sender name" — company or your name. Appears in the 'From' field of the recipient's mailbox.
Click the [Next step] button to connect your mailbox.
