Subscription trap / hidden billing

Technical domain serving Customer.io's in-app messaging scripts with clean scans and 6.7-year domain history. A "free trial" or "$1 trial" combined with auto-renew language means your card will be charged repeatedly. Call your bank to block the merchant if you signed up.

These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

What this means for you

You were probably about to start a 'free' or $1 trial.

The trial auto-renews into repeated charges on your card, with a cancellation process designed to be hard to find.

How this scam works

The trap, step by step

  1. A “free” or $1 trial is offered for something you want.

  2. Signing up quietly enrols you in auto-renewing charges.

  3. The recurring fees start hitting your card.

  4. Cancelling is made deliberately hard to find.

Recognising the pattern is the best defence — if a site follows these steps, close it and don't enter anything.

Confidence
The domain gist.build has existed since November 2019 and resolves to infrastructure that powers Customer.io's customer engagement features. Our antivirus network returned zero detections across 92 engines and the hosting IP carries no abuse reports. The page content matches the official Customer.io marketing site, including their documented subdomains for forms and messaging. Evidence from our research confirms this is a verified technical asset rather than a consumer-facing storefront. The push-notification prompt and scam-family template matches are standard SaaS behaviors, not indicators of malicious intent. No scam reports or complaints appear in the evidence package.

The full analysis

Page Content

The page displays the official Customer.io marketing site titled "Automate Your In-App Messaging | Customer.io". It describes in-app messaging features, omnichannel campaign tools, and analytics dashboards. Four phone numbers and four social links appear, but no contact email or postal address is listed. The page requests browser push-notification permission, a common pattern for SaaS platforms. External scripts load from googletagmanager.com and multiple customer.io subdomains.

Infrastructure

The domain resolves to IP 172.67.69.25 with an abuse score of 0/100 and zero abuse reports. SSL is valid and issued by Let's Encrypt with 59 days remaining. Four cross-domain redirects occur before the final page loads. The domain is not flagged by our sandbox or any browser blocklist feeds.

Domain History

WHOIS records show the domain was registered on 2019-11-17 through NameCheap, Inc. with privacy protection disabled. At 6.7 years old, the domain predates most scam campaigns and aligns with the established Customer.io service timeline. No recent ownership changes are indicated.

Web Reputation

Our research found zero scam reports, zero complaints, and zero positive review mentions. Business registration lookups returned no standalone company record because the domain functions as technical infrastructure rather than a consumer brand. Multiple technical sources confirm subdomains such as api.gist.build and renderer.gist.build belong to Customer.io's integration stack.

What this means for you

The domain is a legitimate backend component of the Customer.io platform. Visitors will not encounter payment forms or credential requests here. The site poses no known risk to users browsing or interacting with Customer.io's messaging features.

AI Recommendation
Safe to visit. This is backend infrastructure for Customer.io, not a consumer site. No payment details or login credentials are requested here.

    This scan re-ran every check; the current findings are detailed above.

gist.build is an established domain now carrying threat signals. An older domain that starts tripping security checks is a classic pattern for an asset that was sold, repurposed, or compromised — the age alone is not reassurance.

Technical Details

The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

Contact Verification

We fetched the page and looked for real-world contact details. Legitimate businesses almost always publish an email on their own domain, a phone number, and a postal address. Scam shops usually don't.

What to do

Subscription trap / negative-option billing

This page combines a "free trial" or "$1 trial" pitch with auto-renew / rebill language — a classic negative-option billing trap.

  • Do not interact with gist.build

    Do not enter credentials, deposit money, download files, or install browser extensions from this site.

  • Your card will be charged the full price after the trial

    Most subscription traps bill the full amount ($49-$149) 14 days after sign-up, and every month thereafter. "Cancel anytime" often means you must call a foreign support line that's deliberately hard to reach.

  • If you already signed up — call your bank today

    Ask your bank to block future charges from the merchant and dispute any charges already made. Many banks will issue a new card number to prevent recurring billing. Save the confirmation email as evidence.

  • Report the billing scheme

    Report to the FTC (reportfraud.ftc.gov) or your national consumer-protection body — subscription traps are specifically illegal in most jurisdictions when the auto-bill terms aren't clearly disclosed.

Safety FAQ

Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.

  • gist.build shows every sign of being a subscription trap — we recommend against paying or entering card details. The domain is 6.7 years old through NameCheap, Inc.. This pattern matches throwaway sites built to take money or data and disappear.
  • No — gist.build scored just 20/100 on our trust scale, and we detected active threat indicators. We recommend avoiding it entirely: don't log in, pay, download anything, or connect a wallet.
  • If you've already paid or handed over details on gist.build, act quickly. 1) Contact your bank or card issuer immediately and ask to dispute the charge or open a chargeback — the sooner you act, the better your odds. 2) Report the site to the U.S. FTC at reportfraud.ftc.gov or the FBI's IC3 at ic3.gov, and in the UK to Action Fraud at actionfraud.police.uk. 3) If you entered a password, change it on gist.build and anywhere you reused it, and turn on two-factor authentication. 4) Watch your bank and email for follow-up fraud, and keep screenshots as evidence.
  • Often yes, if you act fast. Payments made by credit or debit card can frequently be reversed through a chargeback or dispute — contact your bank right away and explain it was a fraudulent site. Bank transfers and gift-card or voucher payments are much harder to recover, but you should still report them to your bank and to the FTC (reportfraud.ftc.gov) or Action Fraud (actionfraud.police.uk). Avoid any "refund" or "recovery" service that contacts you first — it's usually a follow-up scam.
  • That's the classic pattern of a fake or non-delivery shop. These sites take payment for products that never ship, or send cheap counterfeits, then go quiet and eventually disappear. If you paid by card, contact your bank about a chargeback for "goods not received." Keep your order confirmation and any messages, don't pay extra "customs" or "release" fees they may demand, and report the store so others are warned.
  • You can report gist.build through several official channels: the U.S. FTC at reportfraud.ftc.gov, the FBI's Internet Crime Complaint Center (IC3) at ic3.gov, and — in the UK — Action Fraud at actionfraud.police.uk. You can also flag it to Google Safe Browsing (safebrowsing.google.com/safebrowsing/report_phish) so other browsers warn about it, and report it to the company being impersonated if there is one. Reporting helps get scam sites taken down faster.
  • Modern scams are built to look convincing. A valid SSL padlock, a polished template, stock photos, fake reviews, and a trust badge can all be added in minutes and prove nothing about who runs the site. Scammers buy cheap domains, clone real designs, and copy legal pages wholesale. That's exactly why an automated review that checks the domain's age, hosting, blacklists, and behaviour — rather than just how the page looks — is more reliable than a first impression.
  • No — all 92 antivirus and blocklist engines in our malware network currently report gist.build as clean. That's a good sign, though antivirus coverage is only one of the many signals we weigh, and brand-new scam sites can appear clean before vendors catch up.
  • No — gist.build is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.
  • gist.build is 6.7 years old, registered on November 17, 2019 through NameCheap, Inc.. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.
  • gist.build resolves to an IP operated by Cloudflare, Inc. in US (Content Delivery Network). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.
  • This report is a record of the scan run on July 15, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about gist.build has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
