What's Included

Everything Needed for Perfect Deliverability

Not just dropping in a TXT record — a complete audit, fix, verification, and documentation of your entire email authentication stack.

SPF Record Setup

Authorised mail server record added to your DNS zone. Prevents spammers from spoofing your domain in the envelope sender address.

DKIM Configuration

2048-bit DKIM key generated, published to DNS, and signing enabled in your email platform — confirmed via header inspection.

DMARC Policy Rollout

Progressive p=none → p=quarantine → p=reject rollout with aggregate reporting so you monitor before enforcing.

DNS Audit & Cleanup

Full DNS record audit to find conflicts, duplicate SPF lookups, broken CNAME chains, and misconfigured MX records.

Blacklist Removal

Domain and IP blacklist check across 100+ databases. Removal request guidance for any active listings affecting deliverability.

Third-Party Sender Auth

SPF includes and DKIM keys added for all bulk senders — Mailchimp, HubSpot, SendGrid, Brevo, ActiveCampaign, and more.

DMARC Reporting Setup

Aggregate (rua) and forensic (ruf) DMARC reports configured and explained — see who is sending email on behalf of your domain.

Inbox Delivery Testing

Send-and-receive tests to Gmail, Outlook, and Yahoo. Header inspection confirms SPF PASS, DKIM PASS, DMARC PASS across all platforms.

Our Process

From Broken Auth
to Inbox-Ready in 24–48 Hours

We've fixed hundreds of broken SPF, DKIM, and DMARC configurations. Our systematic approach finds every issue — not just the obvious ones.

“Our emails were going straight to spam for 3 weeks. We lost two client deals because of it. Workspace Migration diagnosed the issue in minutes — broken DKIM selector — and had us fully fixed with SPF, DKIM, and DMARC enforced within 24 hours. Inbox delivery is now 100%.”

“Our email open rates went from 12% to 44% after they fixed our authentication. Turns out our SPF record had a syntax error and DMARC was rejecting half our outbound mail silently. Incredibly thorough service — they explained everything as they went.”

“We needed HIPAA-compliant email authentication for our Microsoft 365 environment. They set up SPF, DKIM with 2048-bit keys, DMARC with aggregate reporting to our compliance inbox, and BIMI configuration. Everything documented perfectly for our audit.”

“Our Shopify order confirmation emails were landing in Gmail's Promotions tab and Outlook's junk folder. After the DMARC enforcement and BIMI setup, customers started complaining less and our transactional email deliverability went through the roof.”

“We had two domains with conflicting SPF records because of an old email provider we forgot to remove. Workspace Migration cleaned up the entire DNS zone, set correct flattened SPF, enabled DKIM for Google Workspace, and deployed a monitored DMARC policy. No more spam issues.”

“Blacklisted on Spamhaus and SURBL simultaneously — our sales team couldn't send a single email without it bouncing. Within 48 hours Workspace Migration had us delisted, implemented proper authentication, and set up ongoing monitoring. Lifesavers.”

FAQ

Common Questions

Everything you need to know about fixing your email authentication.

Send yourself an email and check the raw headers — look for "spf=fail", "dkim=fail", or "dmarc=fail". Or use MXToolbox.com — paste your domain and it will flag every misconfiguration immediately.

The most common reason is DMARC alignment failure — SPF and DKIM may pass individually but the "From" domain doesn't align with the authenticated domain. Another common cause is being on an IP or domain blacklist. We diagnose and fix both.

Not if done correctly. We always start with p=none (monitor only) so nothing changes for your email flow while we audit. We only escalate to p=quarantine or p=reject after confirming your legitimate senders are all authenticated.

Yes — every bulk sender needs its own DKIM key published in your DNS and must be included in your SPF record. We handle all of this as part of the Full Setup service.

DNS propagation typically takes 24–48 hours globally, though most providers propagate within a few hours. We verify propagation using multiple global checking tools before marking the project complete.

Yes. We check 100+ blacklist databases, identify the root cause, fix the authentication issue, and guide you through the delisting request process. Most removals happen within 24–72 hours of request submission.
