The Importance of Email List Validation
5 min read
Know which addresses will bounce before you send.
Upload your list and Analyzemail checks every address: its syntax, its domain’s mail records, disposable and role accounts, catch-all servers, and whether the mailbox exists. You get back a list you can send to with confidence.
Pay as you go from $0.010 per address. One credit checks one email.

From a messy export to a list you can send to
No software to install. Everything happens in your Analyzemail account.

We check every address
Each address goes through local checks, then its domain’s DNS and mail server. You can follow progress while it runs.

Twelve checks on every address
Some problems are visible in the address itself. Others only show up when you ask the domain and its mail server. Analyzemail does both, and tells you which check flagged each address.
How each check worksFrom the address and your list
- Syntax
- Addresses that are malformed and can never receive mail.
- Duplicates
- Repeated addresses, so each person is counted and emailed once.
- Disposable domains
- Throwaway inboxes from temporary email services.
- Role accounts
- Shared inboxes such as info@, sales@ and support@.
- Free providers
- Personal addresses at free webmail providers.
- Known litigators
- Addresses and domains on known serial-litigator lists.
From the domain and its mail server
- MX and DNS records
- Domains with no mail servers or broken DNS.
- Parked domains
- Domains parked with a registrar rather than in use.
- Protected domains
- Domains behind security gateways that are likely to filter or trap mail.
- Spam-trap patterns
- Domains whose mail setup matches known spam-trap patterns.
- Catch-all domains
- Servers that accept every address, so a mailbox cannot be confirmed.
- SMTP mailbox check
- Asks the mail server whether the mailbox exists, without sending an email.
Pay for the addresses you check
One credit checks one email address. The more you buy at once, the less each credit costs: from $0.010 per address for up to 5,000, down to $0.001 from 2,000,000 addresses. Monthly and annual plans use the same rates.
| List size | Per address | Total |
|---|---|---|
| 5,000 | $0.010 | $50 |
| 25,000 | $0.007 | $175 |
| 100,000 | $0.005 | $500 |
| 1,000,000 | $0.002 | $2,000 |
