Create your account and verify your sending email domain
Go to kit.com and sign up with your email address. Kit will send you a verification email — click the link before doing anything else. An unverified account has sending restrictions that will silently limit you.
Set your sender name and email address
Navigate to Settings → Email and set your From name and From email address. Your From name should be your personal name, your brand name, or a combination (e.g., “Alex from Indie Maker”). Avoid generic names like “Newsletter” or “Team”. Your From email address should come from your own domain — not Gmail, Yahoo, or any free provider.
Add your physical address for compliance
Go to Settings → Email and scroll to the address section. Enter a physical mailing address. This is legally required by CAN-SPAM in the US and is standard compliance practice globally. Kit automatically appends this address to every email footer.
Connect your custom sending domain
In Settings → Email, find the Custom Sending Domain section and enter your domain (e.g.,
yourdomain.com). Kit will generate the DNS records you need to add — specifically an SPF record and two DKIM records.Add the DNS records to your domain registrar
Log in to your domain registrar (Cloudflare, Namecheap, GoDaddy, etc.) and add the SPF and DKIM records that Kit provides. SPF authorises Kit’s servers to send on behalf of your domain. DKIM cryptographically signs outgoing emails so receiving servers can verify they’re genuine. Both are essential for deliverability.
