Remove invalid, risky and disposable emails before you send. Bulk upload or API checks to cut bounces and protect your sender reputation.
An email validation service checks every address on your list and tells you which ones are real, which ones will bounce, and which ones are risky. You remove the bad ones before you send, so more of your emails reach real people and your sender reputation stays healthy.
If your last campaign had a lot of bounces, or your emails seem to be landing in spam, your list is the first place to look.
Sending to bad addresses costs you more than the wasted emails.
Every address goes through a full battery of checks before you send:
| Check | What it catches | Example |
|---|---|---|
| Syntax check | Addresses written incorrectly | name@@company.com |
| Domain check | Domains that don't exist or can't receive mail | name@compnay.xyz |
| Mailbox check | Addresses where the mailbox itself doesn't exist | oldstaff@realcompany.com |
| Disposable email detection | Temporary addresses used for throwaway signups | 10-minute inbox addresses |
| Role-based address flag | Shared inboxes that often have low engagement | info@, sales@, support@ |
| Catch-all detection | Domains that accept all mail, so a real mailbox can't be confirmed | any-name@catchalldomain.com |
| Typo correction | Common domain slip-ups | name@gmial.com |
| Duplicate removal | The same address listed more than once | repeated rows |
Every address comes back in one of four groups, so you know exactly what to do.
| Result | What it means | What to do |
|---|---|---|
| Valid | The address exists and can receive mail | Send as normal |
| Invalid | The address will bounce | Remove it |
| Risky | Catch-all, role-based or disposable address, delivery uncertain | Send carefully, or exclude from big campaigns |
| Unknown | The server didn't answer clearly | Retry later, or treat as risky |
We'd rather be upfront, because no honest provider can promise otherwise.
We treat every list as confidential business data. Uploaded contact lists are processed over secure SSL connections and are automatically deleted after processing. We never share, sell, or rent your email lists to anyone.
Validation works best alongside a good sending setup. If you're building campaigns, see our email marketing services and bulk email service, our campaign tools, our DND filter for phone numbers, and our email automation options for follow-up sequences, tracked in your lead management system.
It's a service that checks whether email addresses are real and safe to send to. It flags invalid, risky and disposable addresses so you can remove them before sending.
People use the two terms interchangeably. Both mean checking an address before you send. Some providers use "validation" for the syntax and domain checks and "verification" for the mailbox check.
It's very good at catching invalid and mistyped addresses, but no service can be 100% accurate. Catch-all domains and servers that don't respond clearly will always leave a small group of uncertain results.
Before every large campaign, and at least every few months for active lists. Validate new signups in real time if you can.
Yes. Upload your list as a file (.csv, .xlsx) and get a cleaned, labelled version back.
You'll send to fewer addresses, but more of them will actually arrive. Most senders see better delivery and engagement after cleaning because their reputation improves.
Pricing is based on list volume, with transparent tier rates so you only pay for what you check. See our pricing or contact our team for a quote that fits your list size.
Tell us roughly how many addresses you have and where they came from, and we'll show you what a cleaning would look like. Get a quote or book a free demo.
