Use your Sparkpost Account to Send Customer.io
Customer.io supports using your own Sparkpost account to send email with zero loss in functionality. To do this there are two places you’ll need to change settings:
1. On Sparkpost
First, you need to point Sparkpost’s webhooks at Customer.io and get your SMTP information.
Point Sparkpost’s webhooks at Customer.io
Add the webhook URL for your Customer.io account region on the Sparkpost webhooks page for every domain you’ll be sending via Customer.io:
- US:
https://track.customer.io/sparkpost/events - EU:
https://track-eu.customer.io/sparkpost/events
Use the correct URL for your region
track-eu. We redirect traffic from US endpoints to EU-based accounts, however the traffic still passes through US servers and data may be logged in the US.
WARNING!
If you want to track opens and clicks via Sparkpost only, you can change the sending behavior on an email by email basis.
Create a new SMTP delivery key
From the Sparkpost API keys page, you will need to create a new key for use in sending via Customer.io
Save or copy the generated key as you will need it for configuring your SMTP in Customer.io, and can only access it once!
2. In Customer.io
Configure custom SMTP settings
First, head to Workspace Settings -> Email -> Custom SMTP Settings and click the Add Custom SMTP Server button:
Then add in your Sparkpost SMTP credentials:
| Field | Value |
|---|---|
| Address | smtp.sparkpostmail.com |
| Port | 587 |
| Authentication | Login |
| User name | [Your SMTP User Name] |
| Password | [Your SMTP Password] |
When you save your settings, we’ll start sending emails through your Sparkpost account.
Success!
Your account is now set up to send email through Sparkpost. If you have any questions or feedback about setting this up, just get in touch and we’ll be happy to help!
