How to check your spam score before you launch

The Spam Score checker shows you how a real email from your account looks to spam filters, before your prospects find out the hard way. It sends an actual message through your connected account to mail-tester.com and brings the full deliverability report back into Swyftreach.

Run a check

1. Open Spam Score from the sidebar. You need at least one active email account.
2. Choose the account you want to test.
3. Send the test email and wait for the report.
4. Work through anything flagged, then run the check again to confirm the fix.

What the report covers

• SPF: whether your domain authorizes the server that sent the email.
• DKIM: whether the message carries a valid signature for your domain.
• DMARC: whether your domain publishes a policy telling providers how to treat mail that fails authentication.
• Blacklists: whether your sending domain or server appears on public blocklists.
• Content: formatting, links and wording that commonly trigger filters.

Fixing the most common problems

• Missing SPF: publish a single TXT record on your sending domain that includes your provider, for example v=spf1 include:_spf.google.com ~all for Google Workspace. A domain must have only one SPF record.
• Missing DKIM: generate a DKIM key in your email provider's admin console (in Google Workspace: Apps → Google Workspace → Gmail → Authenticate email) and publish the TXT record it gives you.
• Missing DMARC: add a TXT record at _dmarc.yourdomain.com such as v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com. Start at p=none, review the reports, then tighten the policy.
• Blacklisted: stop sending from the affected account, find the cause (usually a volume spike or a poor list), follow the blocklist's delisting process, and warm up again before resuming.
• Content warnings: cut images and links, avoid link shorteners and hype phrasing, and keep the email short and plain.
