Your emails are going to spam. Let's fix that.

from $400

Missing SPF, DKIM or DMARC records mean Gmail and Outlook don't trust your emails, and anyone can send mail pretending to be you. We set them up properly and test delivery.

What this is costing you

  • Sign-ups that never confirm

    If the confirmation email lands in spam, the user never activates.

  • Password resets that never arrive

    Every missing reset email is a support ticket or a lost customer.

  • Someone else sending as you

    Without the right records, scammers can send email that looks like it's from your domain.

Why it usually happens

  • No SPF, DKIM or DMARC records for the domain
  • The email service connected without verifying the domain
  • Emails sent from a shared or default sender address
  • Old records left from a previous provider

Which one it is on your site is the first thing we find out. Send us your report.

What it costs

Every project is a fixed price agreed in writing before we start, with half up front and half at launch. Not sure which fits? The call is free and you leave with a recommendation and a number.

More on the Coding With Douglas channel

Douglas Maringa, the developer behind JetBuild Studio

One senior developer, not an agency relay.

When you work with JetBuild you talk to the person writing the code. No account managers, no handoffs, no telephone game between you and the build. That's why fixed prices are possible, and why 90% of clients come back.

About DouglasLinkedIn

How it works

  1. 1

    Send your report

    Use the form below. Your LaunchProof report comes with it, so we already know what's wrong.

  2. 2

    Fixed price in 24 hours

    We look at the report and your site and reply with a fixed price and a start date. No call required.

  3. 3

    We fix it

    Read-only access until you approve. You see every change on a staging link before it goes live.

  4. 4

    Re-scan as proof

    We run LaunchProof again and send you the clean result, plus a short record of what changed.

How every project runs

Fixed price before we start

You know the full number upfront. Never hourly surprises.

Weekly staging links

You click through the real build yourself. No curated demos.

Documented handover

Any future developer can pick your project up.

You own everything

Code, data, accounts and infrastructure are yours at the end.

  • Fast, reliable, and actually understands Bubble at a deep level.

    “JetBuild delivered exactly what we scoped, on time, with zero hand-holding needed. They understand Bubble at a production level, not just getting things to work, but building them properly.”

    Brian Luerssen, Founder at DraftBit

  • Rescued our app after our first developer disappeared.

    “Our first developer ghosted us halfway through the build. JetBuild picked up the project, restructured the database, and launched it in under 3 weeks. Should have started with them.”

    Rachel Simmons, Founder at PivotOps

  • Built our entire booking system and payment flow from scratch.

    “We needed a booking platform with Stripe payouts and role-based dashboards. JetBuild scoped it clearly, built it fast, and it worked on day one. No back and forth, no surprises.”

    Marcus Webb, Co-Founder at GreenRoute Logistics

“Fixed what our previous developer couldn't finish.”
Christopher Clemmons, National Dental Service

Questions founders ask first

Almost never. We configure the one you already use.

Because the LaunchProof report has already done the diagnosis. We know exactly what to fix, so a job that would normally start with a week of discovery starts on day one.

We tell you before doing anything extra, with a price. The fixed price you agreed never changes without your yes.

Lovable, Bolt, Base44, Replit, v0, Cursor and Claude Code output, Bubble, Supabase and Firebase, plain React and Next.js, and React Native.

Always. Everything stays in your accounts and your repository.
