You will need to supply the domain the order relates to and a short brief describing your setup.

Emails landing in the spam folder is a familiar and expensive problem, and it is nearly always down to authentication records that are missing or set up incorrectly rather than the content of the message itself.

I focus on tracking down and correcting email deliverability faults. Across 17 years working with mail servers and hosting infrastructure, I have helped restore inbox placement for organisations by correctly setting up SPF, DKIM and DMARC, rebuilding sending reputation and clearing blacklist entries.

Why messages get filtered as spam

Providers such as Gmail, Outlook and Yahoo rely on SPF, DKIM and DMARC to confirm that a message truly originates from your domain and has not been altered. When any of these records is absent or wrong, messages are far more likely to be marked as spam, regardless of how legitimate the content is.

SPF lists which servers are permitted to send mail for your domain. DKIM attaches a cryptographic signature confirming the message was not changed in transit. DMARC links the two together and instructs receiving servers on how to treat mail that fails these checks.

What the work involves

I begin by reviewing your current setup to find what is missing or broken, then configure all three records correctly and test them against major providers to confirm they pass authentication. Where a domain or sending IP has been blacklisted, I identify the affected lists and submit removal requests.

For senders using AWS SES, I also cover reputation repair, requests to raise sending limits, IP warm-up planning and reducing bounce and complaint rates. I support all the common platforms, including Google Workspace, Microsoft 365, SendGrid, Mailgun, Postfix, Exim and custom SMTP servers.

DNS providers I work with

Record changes can be made across Cloudflare, AWS Route 53, GoDaddy, Namecheap, Google Domains, or any provider that allows access to DNS management. Whatever your mail is used for, from transactional messages to marketing campaigns or day-to-day business email, the aim is to get it reaching the inbox.

Work carried out has covered AWS, Azure and GCP environments, drawing on experience gathered across more than 330 completed projects.

What happens after you buy

Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.

Questions people ask

How do I know if my SPF, DKIM, and DMARC are properly configured?

A complete review of your current records is carried out, testing authentication against the major providers, followed by a clear report on what works, what is broken, and what is missing entirely.

Will this fix emails going to spam?

In most cases, correctly configured SPF, DKIM and DMARC records resolve the underlying deliverability problem. Where blacklisting or a poor sending reputation is also involved, the Full Deliverability Fix and Enterprise Email Overhaul packages address those additional issues.

Do you work with AWS SES?

Yes. This covers AWS SES setup, reputation repair, requests to raise sending limits, IP warm-up, handling bounces and complaints, and applying configuration best practice.

Which DNS providers do you support?

Any provider you use, including Cloudflare, AWS Route 53, GoDaddy, Namecheap, Google Domains, or another service where you can manage DNS records directly.

Can you migrate my email to Google Workspace or Microsoft 365?

Yes. The Enterprise Email Overhaul package includes assistance with moving to Google Workspace or Microsoft 365, covering MX record changes, user provisioning and planning the data migration.

How long until I see improvement in deliverability?

SPF and DKIM start working as soon as DNS changes propagate. DMARC data builds up gradually as receiving servers report authentication results, and blacklist removals generally take a short while to process once submitted.
