EMAIL VERIFICATION
Every address, checked at the mailbox, before you send.
Old lists fill up with addresses that look perfect and bounce hard. We verify every one with its real mail server first, so dead mailboxes and dead domains never make it into a campaign.
Checked with the real mail server, not just spelling
Every removal comes with a plain-language reason
Your real reachable count, before you launch
WHY LISTS GO BAD
Your list looks fine. Inbox providers know better.
Every list picks up dead weight over time. People change jobs, abandon old inboxes, or mistype an address when they sign up. None of that shows up when you're looking at a spreadsheet. The address still looks exactly like an address.
The first time you find out is when you send to it, and it bounces. A hard bounce isn't a small thing: inbox providers track them closely, and a list full of dead addresses is the fastest way to convince them your mail isn't wanted, even the mail going to people who do want it.
By the time your reports show the damage, the campaign has already gone out, and the next one starts from a weaker position.
HOW IT WORKS
From import to inbox, checked the whole way.
Every address is tested against its own receiving mail server before a campaign can ever reach it.
You import your list
Upload a spreadsheet or collect sign-ups through your forms. Verification starts right away, while the import is still running.
Each address is tested at the mailbox
We check it directly with its receiving mail server, the same way a real send would, not just whether the format looks valid.
Risky addresses are marked, with a reason
Dead mailboxes, dead domains, and addresses that have complained anywhere on the platform are flagged in plain English.
You see your real reachable count
Before you launch, you know exactly how many addresses will actually receive the campaign, not an estimate.
IN DETAIL
What 'checked' actually means.
Three things happen before a single email leaves your account.
AT THE MAILBOX
Checked with the mail server, not just spelling
A lot of checkers only look at whether an address is formatted correctly. That catches typos, not mailboxes that stopped existing months ago. We go further and verify each address directly with its receiving mail server, the same conversation a real send would have.
That's the difference between an address that looks right and one that will actually receive your email.

NOTHING BAD GETS IN
Dead mailboxes never reach your campaign
Dead mailboxes, dead domains, and addresses that have complained anywhere on the platform are stopped before a campaign can reach them, not flagged afterward in a report.
Every removal comes with a plain-language reason, and the address stays on your list marked as removed. Nothing just disappears, so your numbers always add up.

BEFORE YOU LAUNCH
Your real reachable count, not a guess
Verification starts the moment your import finishes, not after you hit send. By the time you're ready to launch, the reachable count on your screen is the real one.
Checking addresses uses credits from the same pool as sending, so you're watching one number instead of a separate bill for cleaning your list.

WHAT IT MEANS FOR YOU
Fewer bounces. Better standing. Less cleanup.
Every bounce you prevent protects a sending reputation you haven't even built up yet.
Bounces prevented, not just counted
Every address is checked before you send, so hard bounces don't happen in the first place.
A reachable count you can actually trust
You see the real number of addresses that will receive your campaign, before you launch it, not an estimate after the fact.
A list that always adds up
Removed addresses stay on your list, marked with the reason, so your total never mysteriously shrinks.
Complaints stay out of future campaigns
An address that complains anywhere on the platform never enters another send.
A reputation you're not defending
Fewer hard bounces means inbox providers keep trusting the mail that comes from your domain.
COMPARED
What a typical platform skips.
A typical email platform
- Checks spelling only. Confirms the format looks right and little else.
- Bounces measured after the fact. You find out once your reputation takes the hit.
- Removed addresses vanish. Your list total quietly shrinks with no explanation.
- Verification is a separate step or add-on. Another thing to buy and run.
- No record of a complaint. The same address can end up on a list again.
Six and Two
- Checks the mailbox itself. Verifies with the real receiving mail server before you send.
- Bounces prevented. Dead addresses are removed before a campaign ever reaches them.
- Every removal explained. The address stays on your list, marked with a plain-language reason.
- Verification runs automatically. It starts the moment your list finishes importing.
- Complaints block future sends. An address that's complained anywhere never enters another campaign.
QUESTIONS
Everything you're wondering about verification.
Why did my list get smaller?
Some addresses no longer have a working mailbox. Each one is marked with the reason, and stays on your list as a record, so you can see exactly why.
Does verification check more than spelling?
Yes. Each address is tested with its real receiving mail server, the same way a send would reach it, not just checked for a valid format.
When does verification happen?
It starts as soon as your list finishes importing, before you ever build a campaign. By the time you're ready to launch, the reachable count you see is the real one.
Does verification cost extra?
No separate bill. Checking addresses uses credits from the same pool as sending, so you're watching one number, not two.
What happens to addresses that get removed?
They stay on your list, marked as removed with the reason attached. Nothing disappears, so your numbers always add up.
Can someone who complained get emailed again?
No. An address that has complained anywhere on the platform is kept out of every future campaign.
Does this replace good list-building habits?
No, but it catches what good habits miss: mailboxes that have gone dead since someone signed up, or domains that no longer exist. Pair it with sign-up forms and your list stays healthy over time.
Does this cover CAN-SPAM compliance?
Verification confirms an address can receive mail. You're still responsible for honest headers, a physical address, and honoring opt-outs within 10 business days under the CAN-SPAM Act.
WORKS WITH
Part of a list that stays healthy.
Verification is one piece. These keep the rest of your list in good shape.
Lists and imports
Bring your list from any spreadsheet. The importer maps every column to a field and resumes an interrupted upload right where it stopped.
Segments and follow-ups
Save the people who clicked, opened, or didn't, from any campaign you've sent, and follow up with a new subject line.
