Custom Email Trick (That Costs $0)
Step 1: Free domain
- Visit Freenom.
- Register a domain (e.g.,
yourname.tk
) — it’s free. - Choose
.tk
,.ml
,.ga
, etc. because… free is a lifestyle.
Step 2: Free inbox (2 options)
A. Zoho Mail (full inbox)
- Go to Zoho Mail Free Plan.
- Sign up for the Free tier (5 users allowed).
- Add domain from Freenom.
- Verify domain by updating DNS TXT record in Freenom.
- Set up your email (e.g.,
[email protected]
).
B. ImprovMX + Gmail (forward-only)
- Go to ImprovMX.
- Point domain MX records from Freenom to ImprovMX.
- Set forwarding to your Gmail.
- Use email like
[email protected]
, still counts as “company email.”
Sign-Up Flow (Don’t Blink)
- Go to CustomGPT.ai.
- Click “Start Free 8-Day Trial.”
- Use your custom domain email.
- On checkout screen, paste:
JOINSECRET99
- Watch the price drop to $0.
- Choose payment method (still required, even at $0).
- Start trial.

Clone More Free Trials (Email Alias Hack)
- Gmail lets you add
+alias
to your email: - CustomGPT blocks Gmail, but works with alias versions of custom domains:
- Each new alias = another free trial. [Modern alchemy.]
Reality Check
Gmail/Yahoo/Outlook = Blocked from signup.
Only work emails pass. Yes, even if you moonlight as CEO of
potatoenterprises.tk
.Payment info is required (Stripe), even if total = $0.
You can cancel anytime during the free window.
Warnings

compliance?, of course)
- This is 100% legal. No pigeons were harmed.
- Think of it as coupon clipping for the AI age.
- If the signup gatekeeper had a personality, it’d be that smug bouncer outside the exclusive VIP tech club. Spoiler: You’re getting in anyway.
