What I fix
I’m a retired sysadmin who chose to spend retirement on the one thing nobody else wants to touch: DNS. These are the calls I take every week.
Google & Microsoft sender rules
The 2024 bulk-sender requirements caught a lot of businesses off guard. If your newsletters or transactional mail suddenly bounces or hits spam, this is almost always the cause — and it’s fixable.
Newsletter platform setup
I’m a MailerLite Certified Expert — seven certifications through MailerLite Academy covering email deliverability, sender authentication, automation, landing pages, and e-commerce. Same comfort level with Mailchimp, ConvertKit, Beehiiv, ActiveCampaign, Brevo, Sendgrid, and Postmark: the right CNAMEs, TXT records, and verification bits in place so your sends authenticate properly.
Broken MX & mail routing
Email vanishing, bouncing, or going to the wrong inbox? We trace the records, the routing, and the priorities, and put them back the way they should be.
Domain & registrar moves
Migrating between Cloudflare, GoDaddy, SiteGround, Hostinger, Bluehost, Namecheap, Google Domains / Squarespace, AWS Route 53, IONOS, or anywhere else — without dropping mail or breaking the website during the cutover.
“I don’t even know what’s wrong”
Honestly the most common booking. We hop on Zoom, I look at your records, and we figure out what’s actually broken. No judgment — DNS is genuinely confusing.
How it works
-
Book a 1-hour slot
Pick any open time on the calendar. Payment runs through Stripe at the moment of booking — $85 for the hour, plus $10 if you want the call recorded.
-
Hop on Zoom
You share your screen, or you give me temporary remote control — your choice. Either way you watch every single change as I make it.
-
I never touch your passwords
You stay logged in to your registrar and DNS host. I guide and click, you approve. When the call ends, my access ends.
-
You leave with it fixed
Most sessions end with everything working and a clear note of what changed. If you paid for the recording, the download link lands in your inbox right after.
Pricing
No subscriptions, no retainers, no surprise invoices. You book the hour you need.

About me
I’m Michal Ferber — better known online as TechGuyWithABeard. I’m retired, I don’t take on full-time clients, I don’t run a marketing funnel, I don’t have a team. I take a small number of DNS calls a week because, after a long career, troubleshooting DNS is the part I still actually enjoy.
That means when you book me you get a one-on-one session focused entirely on your problem — not an assistant, not a ticket queue, not a script. I’ve spent years on DMARC, SPF, DKIM, mail routing, registrar migrations, and every quirky newsletter platform in the wild. I’m a MailerLite Certified Expert — seven certifications through MailerLite Academy covering deliverability, sender authentication, and the rest — fluent in the broader field, and if it touches DNS I’ve probably fixed it before.

- Decades hands-on with DNS, email, and registrars

Frequently asked questions
Do you need my domain registrar or DNS host password?
No. I never ask for and never accept passwords. We work together over Zoom — either I guide while you click, or you grant me temporary remote control. You see every change as it happens, and access ends when the call ends.
How long does a typical DNS fix take?
About 90% of the issues I see — failing DMARC, broken SPF, missing DKIM, newsletter sender verification, mis-pointed MX records — are resolved in well under an hour. Sessions are booked in 1-hour blocks at $85.
Can you help with the new Google and Microsoft sender requirements?
Yes. The 2024 bulk-sender rules from Google, Yahoo, and Microsoft caught a lot of small businesses off guard. I’ll get aligned SPF, DKIM, and DMARC published correctly so your mail stops bouncing or landing in spam.
Are you actually MailerLite certified?
Yes — MailerLite Certified Expert, with seven certifications through MailerLite Academy covering email deliverability and spam avoidance, sender authentication fundamentals, automation, landing pages, lead generation, e-commerce, and platform basics. If your newsletter is hitting deliverability issues, sender verification problems, or DNS-side weirdness, I’ve spent real time inside that platform’s quirks.
Which other newsletter and email platforms do you support?
All the popular ones — Mailchimp, ConvertKit (Kit), Beehiiv, Substack, ActiveCampaign, Brevo (Sendinblue), Klaviyo, Constant Contact, Campaign Monitor, AWeber, GetResponse, Drip, Flodesk, HubSpot, Omnisend, MailPoet, Sendgrid, Postmark, Mailgun, Mailjet, Amazon SES, Resend, and more. If your platform issues DNS records to verify, we can get them in place.
Which registrars and DNS hosts do you work with?
All of them. The big ones I see most often: Cloudflare, GoDaddy, SiteGround, Hostinger, Namecheap, Bluehost, HostGator, DreamHost, IONOS (1&1), Network Solutions, Google Domains / Squarespace Domains, AWS Route 53, Hover, Porkbun, Name.com, Domain.com, Dynadot, DNSimple, Gandi, Wix, WordPress.com, Shopify, and the rest. Different control panels, same DNS underneath.
Do you record the session?
Only if you ask. For an extra $10 I’ll record the Zoom call and send you a private download link so you have a permanent reference of every change we made and why.
What if it takes longer than an hour?
If it runs long we can either book a follow-up slot or extend in 1-hour increments. There are no surprise charges — billing is per booked hour through the calendar.
Do you offer refunds?
If we hop on the call and I can’t actually help with your issue, you get a full refund. That’s rare — most things that look like “DNS” really are DNS.
Let’s fix it today.
One hour, $85, and the broken DNS thing that’s been bothering you for weeks is just… done.
