Verifying an Email Domain

Domain verification is required to send from Spark and is an important step to protect your reputation, prevent spoofing, and help your messages reach the inbox.

Registering the domain in Spark is the first step. Verification happens after your network administrator adds the Spark-provided DNS records to your domain host.

Before you start

  • Who to involve: A network administrator or IT person who can edit DNS records at your email domain host (for example, GoDaddy, Cloudflare, Namecheap, DigitalOcean, or Google Domains).
  • What you need: The email domain you plan to send from—the text that appears after the @ symbol in your email address. Do not include www.

Part 1: Register your domain

  1. In Spark, go to Settings → Emails → Registered Domains tab.
  2. Click Register a Domain.
  3. Enter your email domain in the Register a New Domain field. For example, if your address is hello@awesomecompany.com, enter awesomecompany.com.
  4. Click Register.

If your company has already registered a domain, choose it from the Use an existing registered domain for this company list. You can use the same domain on multiple projects, and you only need to verify it once.


Part 2: Verify your domain

Verification is required before you can send emails from Spark. Do not skip these steps.

  1. In Spark, go to Settings → Emails → Registered Domains tab.
  2. Click on the domain to view the Required DNS Records. If you don’t see them right away, refresh the page.
  3. To share the records, select the micromenu (three dots) beside the domain, choose Send DNS Records, enter the recipient’s email address, then click Send DNS Records. We recommend sending the DNS records to yourself and forwarding them to your network admin or IT person so you can provide additional context.
  4. Your network administrator or IT person must save these records to your email domain host.

Important: Registering your domain and emailing the records does not verify your domain. Your network administrator or hosting provider must add these DNS records to your domain host.


Notes for common providers

Some providers, such as GoDaddy may automatically add your domain to certain DNS records, so you may need to adjust the Spark-provided hostname. If you’re unsure how, contact support@spark.re.

More specific instructions for common providers can be found at the links below:

After your admin adds the DNS records

  • Return to the Domain registration page to check the status. It can take 24-48 hours for your domain to verify.
  • Use a DNS Lookup service such as MX Toolbox to check that your records have propagated.
  • If the records have propagatged but your domain is not verified, contact support@spark.re.

New domain? Warm it up

If this is a new domain, warm it up before you start sending large campaigns. Begin with smaller sends and increase volume gradually to protect deliverability.
