Verify Back-in-Stock and Product Launch Notify Lists Before the Drop
A notify-me list is the warmest list a shop owns, and it is mailed the least carefully. People type their address into a small box when a product sells out, nothing checks it, and months later the whole list gets a message in the same hour. That is the moment every typo and dead mailbox shows up together. Verify the list a few days before the restock on the verify page; the first 100 checks are free on a Google sign-in, no card.
What goes wrong on drop day
- Typos stay hidden. Nothing is sent when someone signs up, so
gmial.comsits quietly until the day it counts. - Throwaway addresses. Some people use a disposable address to get a notification and never look at it again.
- Age. Items sell out for weeks. Some of those addresses have been dead longer than they have been on your list.
- Bursts. A large send in one go makes a bounce spike obvious to your sending platform. Pause a campaign during a bounce spike tells you what to do if it happens anyway.
Step 1: Export and combine
Export every notify list for the product line and put the addresses in one column. If several products have their own lists, merge them and keep a column for the product, then remove repeats with the remove duplicate emails tool.
Step 2: Repair typos
The email typo corrector fixes common domain slips. Read the changes before you accept them.
Step 3: Verify four to seven days before
Upload the file to the verify page. Valid, risky or invalid comes back for each row with a reason. Verifying early leaves time to react; verifying the morning of the drop does not.
Step 4: Plan waves
- Wave one: valid addresses, ordered by how long ago they signed up if you want the earliest askers to have first chance.
- Wave two: valid addresses that signed up recently.
- Wave three: risky addresses, after you have seen wave one's bounces.
- Never: invalid addresses. Keep them off the list, but keep a note so a returning shopper can add a correct one.
The send tier splitter cuts a verified file into those groups.
Step 5: Fix the sign-up box
Ask for the address twice or show a prompt when the domain looks wrong, so next season's list starts cleaner. Verify in-store and kiosk sign-ups covers the form side.

Common questions
When should I verify a back-in-stock list?
A few days before the send. That leaves time to fix typos, split off risky rows and plan the send order, and it still catches addresses that have died since sign-up.
Why do notify-me lists bounce on the first send?
Addresses are typed into a small box by people in a hurry, and nothing checks them until the first message. The slips and throwaway addresses all surface at once.
Should I send the notification to everyone at the same moment?
Stock may run out before everyone has a chance, so send in waves if you can. Valid addresses first, risky ones after.
Does a verified list make the drop email land in the inbox?
No. Verification removes addresses that would bounce. Where the message lands also depends on your domain setup, your history and the content.
