Email verification on every address, before anything is sent

Why we check first

Verification is the last step of finding stores, after we have found the store and the person who buys for it. It is there to protect two things.

The first is your sending reputation. Mailboxes that send to addresses that do not exist look careless to the big email providers, and they start sending your mail to junk. A few bad addresses can hurt every email after them.

The second is your time. A list full of dead addresses makes a campaign look like it failed when it never reached anyone.

What the check looks at

Each address is checked before it is added to your campaign. In plain terms we ask:

• Does the address exist? Mail to it should reach a real mailbox.
• Is the domain real and accepting mail? A store website with no working mail server is a dead end.
• Is it a system or service address? No-reply, postmaster and similar boxes are dropped before they are even checked.
• Does it belong to the store? An address on the web designer's domain, picked up from a site footer, is not the store and is left out.

Three outcomes

Every address ends up in one of three places.

1. 1ConfirmedThe check shows a real mailbox at that address. It goes on your list.
2. 2Cannot be confirmedSome stores' mail servers accept every address, so no check can confirm a single one. Unless something marks it as bad, it goes on your list, because for many small shops it is the only way in.
3. 3UndeliverableThe address does not exist or will not take mail. It is dropped, never appears on your list and is never sent to.

What still bounces, and what happens then

No check can see the future. A manager leaves the week after we checked, or a store closes its email. When an email hard-bounces, the address is blocked across all your campaigns and the rest of its follow-ups are cancelled. A soft bounce stops that contact's sequence without blocking the address.

Your sending mailboxes are also protected by how we send: a separate domain that we set up for you, so a bad day never touches your own domain.

What verification cannot tell you

A verified address is a real inbox. It does not mean the person wants your product. That part is up to store search, which picks stores that fit, and the email itself. If a campaign gets few replies, the cause is far more often the offer or the fit than the addresses.

Why this protects your results

Verification is quiet work that you rarely see, but it shapes every number in your campaign report. A campaign sent to unchecked addresses shows a high bounce count and a low reply rate, and it trains email providers to distrust your mailboxes. A campaign sent only to checked addresses gives you an honest reply rate: replies from people who actually received your email.

That honesty matters when you decide what to do next. If a checked list of well-fitted stores still gets few replies, you know to change the offer or the opening line. You are not left guessing whether anyone saw it.

It also saves you money and samples. Every store on a checked list is a real business with a working inbox, so each sample you send after a reply goes somewhere it can be tasted.
