Domains
To send emails with ToSend, you need to verify ownership of your domain by adding DNS records.
Adding a Domain
- Go to Domains in your dashboard
- Click Add Domain
- Enter your domain name (e.g.,
yourdomain.com)
DNS Records
After adding a domain, you'll need to configure three DNS records with your DNS provider.
DKIM Record
DKIM (DomainKeys Identified Mail) verifies that emails are authorized by the domain owner.
| Type | Name | Value |
|---|---|---|
| TXT | tosend._domainkey.yourdomain.com | Provided in dashboard |
The DKIM value is a long string containing your public key. Copy the entire value from your dashboard.
SPF Record
SPF (Sender Policy Framework) authorizes ToSend to send emails on behalf of your domain.
| Type | Name | Value |
|---|---|---|
| TXT | send.yourdomain.com | v=spf1 include:amazonses.com ~all |
MX Record
The MX record enables bounce and complaint handling.
| Type | Name | Priority | Value |
|---|---|---|---|
| MX | send.yourdomain.com | 10 | feedback-smtp.us-east-1.amazonses.com |
DMARC Record (Recommended)
DMARC protects your domain from email spoofing and improves deliverability. Add this after DKIM and SPF are verified.
| Type | Name | Value |
|---|---|---|
| TXT | _dmarc.yourdomain.com | v=DMARC1; p=none; |

Verification Status
After adding DNS records, your domain will go through these statuses:
| Status | Description |
|---|---|
| Pending | DNS records are being verified. This can take up to 72 hours. |
| Verified | Domain is ready to send emails. |
| Failed | DNS records were not detected within 72 hours. Check your configuration. |
DNS Propagation
DNS changes can take up to 48 hours to propagate. If verification fails, double-check your records and try again.

This is limited to 3 emails per domain per day.
