How can I check my domain health?

Your domain health determines whether your emails reach the inbox or land in spam. Three DNS records — SPF, DKIM and DMARC — tell providers like Gmail and Outlook that your emails are genuinely from you.

Missing or misconfigured records are the single most common reason good emails get filtered, no matter how well written they are.

To use:

1. Go to Outreach › Email Deliverability

2. Each of your sending domains is checked automatically and shown as Healthy or Needs attention

3. For any domain that needs attention, follow the suggested fix shown on the card

4. Apply the record at your domain registrar, then reload the page to confirm

What each record does

SPF — lists which servers are allowed to send email for your domain
DKIM — adds a cryptographic signature proving the message wasn't altered
DMARC — tells inbox providers what to do with mail that fails the checks above

Important: DKIM selectors differ between providers. We check the most common ones, so a result of "Not detected" doesn't always mean DKIM is missing — if you set it up with a custom selector, verify directly in your email provider.

For step-by-step setup instructions for your specific registrar and email provider, see the DNS guides in the FAQs.

One-click unsubscribe

Gmail and Yahoo now require bulk senders to support one-click unsubscribe. LeadSwift adds the required List-Unsubscribe header to every email automatically — there is nothing for you to configure.

This puts a native "Unsubscribe" link at the top of your email in Gmail. Anyone using it is added to your unsubscribe list and immediately removed from any sequence they're in, exactly like clicking the unsubscribe link in your email body.

You can review everyone who has opted out on the Unsubscribes page.
