# Add and verify a sending domain

> Choose a sending mode and complete the required DNS configuration

Verify a sending domain before sending email with Sendify. Domain verification protects your sender identity, improves deliverability, and reduces the risk of messages being treated as spam.

## Choose a sending mode

Sendify supports branded sending and platform relay.

| Capability | Branded sending | Platform relay |
| - | - | - |
| Visible From address | Your brand, such as `name@yourcompany.com` | Your brand, such as `name@yourcompany.com` |
| Envelope sender (MailFrom) | Your domain | Sendify's platform domain |
| Brand independence | Highest | Lower because Sendify handles the underlying delivery identity |
| DNS setup | Usually SPF, DKIM, DMARC, and MX | Usually DKIM and DMARC |
| Best for | Teams that need independent reputation and brand alignment | Teams that prioritize faster setup and lower direct domain risk |

### Branded sending

All technical layers of the message use your domain. This gives you the clearest brand identity and an independent sending reputation.

> [!WARNING]
>
> Poor list quality or a high complaint rate can damage your domain reputation and may affect corporate mail. Use a dedicated subdomain such as `service.yourcompany.com` whenever possible.

### Platform relay

Recipients still see your branded From address, while Sendify handles MailFrom and delivery.

![Platform relay notice](https://mintcdn.com/sendify-3a1f7fa4/kc5dBtMpq5V05V0e/platform-relay-warning.png?fit=max\&auto=format\&n=kc5dBtMpq5V05V0e\&q=85\&s=ada88ea12e113e089b8a9b26edc1dc18)

Platform relay requires less DNS configuration, but its shared delivery reputation can be affected by other users. Some strict recipients may also place less trust in a message whose From and MailFrom domains do not align.

## Add a sending domain in Sendify

 `System Management` → `Domain Management`

**1. Enter the sending domain**

Sign in as an administrator and select **Add sending domain**.

![Add a sending domain](https://mintcdn.com/sendify-3a1f7fa4/kc5dBtMpq5V05V0e/add-sending-domain.png?fit=max\&auto=format\&n=kc5dBtMpq5V05V0e\&q=85\&s=420c5e6a9f625694f89d9fe193ec7ed8)

To avoid conflicts with existing SPF and MX records, use a dedicated subdomain such as `mail.yourcompany.com` or `mkt.yourcompany.com`.

**2. Choose a sending mode**

Select branded sending or platform relay based on the tradeoffs above.

**3. Configure DNS records**

At your domain registrar or DNS provider, add or update the host names, record types, and values shown by Sendify.

> [!WARNING]
>
> If an SPF record already exists, update it as instructed. Do not remove existing `include` entries that are required by other mail services.

**4. Wait for verification**

DNS changes normally take a few minutes to several hours to propagate. Sendify checks the records automatically.

**2. Add each DNS record**

Copy each host, record type, and value from Sendify.![Add a DNS record in Alibaba Cloud](https://mintcdn.com/sendify-3a1f7fa4/IaJHUY9fCSXuo_lG/aliyun-add-dns-record.png?fit=max\&auto=format\&n=IaJHUY9fCSXuo_lG\&q=85\&s=d123d027bf5098a187d6406e080a9581)

## DNS record glossary

* **MX:** Identifies the servers that receive mail for your domain.
* **SPF:** Lists the servers allowed to send mail on behalf of your domain.
* **DKIM:** Adds a cryptographic signature that proves the message is authorized and unchanged.
* **DMARC:** Tells receiving providers how to handle messages that fail SPF or DKIM and can produce abuse reports.
* **TXT:** May be used by Sendify to verify that you control the domain.
