SendByte
Start sending

Plan your switch to SendByte.

Tell us your domain and who you send with today. We read your live DNS, merge SendByte into your SPF so both providers can run during the switch, and show you the exact code change. No signup needed.

We only read public DNS. Your DKIM key is generated when you add the domain in SendByte.

Your migration plan

Built from your live DNS, in three parts.

  1. DNS changes

    The SPF record to publish, merged with the one you have, and a DMARC record if you need one.

  2. Checklist

    Ordered steps from adding the domain to cutting over from your current provider.

  3. Code swap

    Your current send call next to the SendByte one, language by language.

What the plan covers

The two fiddly parts of a migration, done for your domain: a safe SPF merge and the code change.

Your SPF record, merged
We read the SPF record you publish today and add the SendByte include before its all mechanism. Your current provider stays in the record, so both can send while you switch.
A DMARC starting point
If you already publish DMARC, the plan tells you to keep it. If you do not, it gives you a monitoring policy to start from and tighten later.
An ordered checklist
Add the domain, publish SPF and DKIM, verify, swap the code, send a test, then cut over once both senders have run side by side.
The code swap
Your current send call next to the SendByte one, with the SendByte side in Node.js, Python, PHP, Go and cURL.
What it cannot show
Your DKIM key. SendByte generates one unique to your domain when you add it in the dashboard, and the dashboard shows the record to publish.
