Email deliverability

Get your email out of spam and into the inbox.

I help newsletters and SaaS teams fix the authentication, reputation and list problems that quietly send their email to spam. By day I look after email delivery at Ghost: about 2 billion emails a year.

Most domains I check have at least one of these. Few people notice until open rates drop.

Sound familiar?

Email problems rarely announce themselves


Open rates fell off a cliff

Nothing changed on your side, but Gmail started putting you in spam.

You're on a blocklist

A bounce message mentions Spamhaus or Microsoft and you're not sure what to do next.

DMARC has been at p=none for years

You set it up once, and nobody has looked at the reports since.

Too many tools send as you

Marketing, product, billing and support email all share one domain, with an SPF record nobody fully understands.

About

Hi, I'm Sam


I'm a software engineer who ended up specialising in email. At Ghost, I'm the engineer responsible for email delivery: the platform behind thousands of newsletters, sending about 2 billion emails a year. When inbox placement goes wrong, I'm the one who gets called.

That means I've seen most of the ways email breaks: DNS records that quietly stopped working, blocklistings, reputation dips after one bad send, and lists that grew faster than their engagement. I bring the same engineering approach to your setup: evidence first, then a clear fix.

I'm based in the UK and work with clients anywhere.

Questions

Frequently asked


Can you guarantee my emails will reach the inbox?

No, and nobody honest can. Gmail, Outlook and Yahoo decide inbox placement using signals they don't publish. What I can do is find and fix everything within your control, which is usually what's causing the problem.

Will you make changes to our systems?

By default, no. I give you exact instructions and your team makes the changes, so you keep control and learn how it works. Hands-on help can be arranged once we've worked together.

Which email platforms do you work with?

Most of them. Deliverability comes down to the same DNS, reputation and list fundamentals whichever platform you use. I regularly work with Mailgun, Amazon SES, SendGrid, Postmark, Mailchimp, Kit, beehiiv, HubSpot and Customer.io.

I publish on Ghost. Can you help?

Please contact Ghost support. Because I work on Ghost's email platform, I don't take Ghost customers as paying clients, and the support team will get your question to the right people.

How quickly can you respond?

I reply to messages within one working day, and calls happen on Fridays. I don't offer an emergency response service. If you're in trouble right now, the Spam Rescue starts within a week.

How do payments work?

Newsletter services are paid upfront. Larger audits are 50% to start and 50% on delivery. Retainers are billed monthly and can be cancelled with a month's notice.

Not sure what's wrong?


Send me your domain. I'll take a look before we talk, and you'll leave the call knowing the top three things to fix, whether or not we work together.
