The problem
Why bad addresses cost you
What goes wrong when a list is not verified.
Customers mistype at checkout
A typo means no receipt, no shipping update and a support ticket.
Throwaway inboxes abuse offers
Disposable sign-ups claim first-order discounts again and again.
Lost post-purchase revenue
Abandoned cart and review emails never reach the customer.
How it works
How SimpleCold fits in
Three steps, using the tools you already have.
- 01
Add a check to checkout
When the email field loses focus, your server calls the API.
- 02
Show the fix
Display Did you mean…? under the field when there is a typo.
- 03
Block or flag throwaways
Reject disposable inboxes on discount sign-ups.
What you get
What changes for your team
Every address comes back with a result and the reason behind it.
Typos fixed before purchase
Customers correct the address while they are still on the page.
Discount abuse reduced
Throwaway inboxes are caught on sign-up offers.
Receipts that arrive
Order and shipping emails reach a real inbox.
Fast at checkout
Most checks answer in seconds, and never block typing.
Slow servers
A slow mail server never costs you a second credit
Some servers make unknown senders wait on purpose. You get an answer in about 12 seconds, and the final result follows by itself.
You click Check
Format, domain, typo, disposable, role and catch-all checks run, then we ask the mail server.
You get an answer
If the server is still stalling, you see Processing instead of a guess.
The final result arrives
Usually within a minute or two. Ask again about that address for free for 30 minutes. No second credit.
