Domain Verification
Do you have any questions on our Email API? Write to us at [email protected].
Verify your sending and tracking domains through the SendClean interface to improve sender reputation and inbox delivery.
Verification overview
Add a DKIM TXT record so receiving mail servers can verify that your emails are sent from your domain.
Add or update an SPF TXT record to authorize SendClean to send email on behalf of your domain.
Add a CNAME record for tracking email opens and link clicks.
Configure verified domains as your sending defaults in SendClean.
DKIM Verification
DKIM (DomainKeys Identified Mail) authentication helps receiving mail servers verify that your emails are sent from your domain.
Steps to Set Up DKIM
- Go to Domain Settings in your SendClean account.
- Add your domain name.
- Send a verification email to confirm domain ownership.
- Go to DKIM Settings to obtain the required TXT record values.
- Create a TXT record in your DNS with the following settings:
| Field | Value |
|---|---|
| Record Type | TXT |
| Hostname | sctrans._domainkey |
| TTL | 3600 or blank |
| Value | (obtain from DKIM Settings in your SendClean account) |
Allow up to 24 hours for your DNS changes to propagate globally.
SPF Records
SPF (Sender Policy Framework) records tell receiving mail servers which IP addresses are authorized to send email on behalf of your domain.
Steps to Set Up SPF
- Check whether your domain already has an SPF record. Existing SPF records begin with
v=spf1. - If no SPF record exists, create a new TXT record with the following settings:
| Field | Value |
|---|---|
| Record Type | TXT |
| Name / Hostname | @ or blank |
| TTL | 3600 or blank |
| Value | (obtain from View SPF Settings in your SendClean account) |
- If an SPF record already exists, add the SendClean include value to it rather than creating a new record.
Multiple SPF records on the same domain can cause authentication failures. Update the existing SPF record instead of creating a second one.
Verifying Your SPF Record
You can verify your SPF record using MXToolBox:
- Go to mxtoolbox.com.
- Enter your domain name.
- Select SPF Record Lookup from the dropdown menu.
- Review the results to confirm your SPF record is correctly configured.
Tracking Domain Setup
A tracking domain is used to track email opens and link clicks. You set it up using a CNAME DNS record.
Steps to Set Up a Tracking Domain
- Go to Tracking Domain Settings in your SendClean account and click View Track Settings to obtain the required CNAME value.
- Create a CNAME record in your DNS with the following settings:
| Field | Value |
|---|---|
| Hostname | delivery |
| Record Type | CNAME |
| Value | (obtain from View Track Settings in your SendClean account) |
Sending Defaults Configuration
After verifying your domains, configure your sending defaults in SendClean:
- Go to Sending Defaults in your account settings.
- Set the following fields:
| Setting | Description |
|---|---|
| Custom Tracking Domain | Your verified tracking domain (e.g. delivery.example.com) |
| Custom SPF/DKIM Signing Domain | Your verified sending domain for SPF/DKIM signing |
| Return Path Domain | Domain to use as the return path (bounce address) |
| Custom Sending Domain | Your verified sending domain |
- Click Save to apply your settings.
