ZapBounce and Privy
Privy's popups typically trade a discount code for an email address. That transaction changes the incentive: somebody who wants the discount and not the newsletter has a reason to supply an address they will never read.
The code goes to that address, which means the customer may not get it either.
The discount code goes to the throwaway address
A shopper enters a disposable address, receives the code there, uses it, and never reads another email from you. That is a working transaction with a worthless subscriber attached.
A shopper who mistypes their address gets no code at all, abandons the cart, and you lose the order the popup was supposed to create.
The second case is the expensive one, and it is the one verification fixes while the shopper is still on the page.
How the data moves
Verify before the code is issued
The code is the thing the shopper is waiting for. Catching a typo before it is sent is what saves the order.
Show the suggestion in the popup
The shopper is present and motivated. A one-click correction has a high acceptance rate at this moment.
Issue the code regardless
Never withhold a discount over a verdict. Show the suggestion and issue it anyway.
Segment disposable subscribers
They took the discount and will not engage. Knowing which ones they are keeps your engagement metrics honest.
Setting it up
- Route the Privy submission through a webhook you control.
- Verify the address before the discount code is dispatched.
- Return a typo suggestion to the popup where your integration allows it.
- Issue the code whatever the verdict says.
- Tag disposable and invalid addresses so the marketing list can exclude them.
- Compare redemption rates between verified and unverified captures after a month.
Privy: common questions
Should I refuse a discount to a disposable address?
Measure it first. You may be refusing a first-time customer who simply guards their inbox.
What does a typo cost here?
The order. The shopper never gets the code and abandons, which is worse than a low-quality subscriber.
Where should the check run?
Between the popup and the code dispatch, so a correction is possible before anything is sent.
