Before you can send email sequences from Prospects, you need to connect and verify at least one sending domain. This protects your email deliverability, keeps outreach out of spam folders, and establishes that you own the domain you're sending from.

What is a sending domain?

A sending domain is the email domain your outreach emails are sent from (e.g. yourcompany.com if you're sending from name@yourcompany.com). Verifying the domain involves adding DNS records that prove ownership and configure email authentication (SPF, DKIM, DMARC).

Adding a sending domain

  1. Open Prospects and click the Domains tab.
  2. Click + New Domain (or Connect domain).
  3. Enter the domain you want to send from (e.g. yourcompany.com).
  4. Euryka provides a set of DNS records to add to your domain registrar (such as Cloudflare, GoDaddy, Namecheap, or Route 53).

Adding DNS records

Log in to your domain registrar and add the records Euryka provides. The records typically include:

Record type Purpose
SPF (TXT) Authorises Euryka's servers to send on behalf of your domain
DKIM (TXT or CNAME) Cryptographically signs outgoing emails
DMARC (TXT) Tells receiving servers what to do if SPF/DKIM checks fail

DNS changes can take a few minutes to a few hours to propagate. Most verifications complete within 30 minutes.

Verifying the domain

  1. Return to the Domains tab in Prospects.
  2. Click Verify next to your domain.
  3. Euryka checks the DNS records and confirms verification.

Once verified, the domain shows a verified status and is available when configuring your email sequences.

Monitoring deliverability

The Domains tab shows a deliverability score for each connected domain. A high deliverability score means your emails are more likely to land in recipients' inboxes. Tips to keep your score high:

  • Warm up new domains by sending low volumes initially
  • Maintain a low bounce rate by keeping your contact data clean
  • Avoid spam-trigger language and long image-heavy emails in your sequences
