Analyzemail

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.

  1. 1

    Upload your list

    Add a CSV or TXT file from your account, or import one from Mailchimp or Constant Contact. Choose which checks to run.

  2. 2

    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.

  3. 3

    Download or sync the results

    Download the full results with the findings for every address, or send the clean list back to Mailchimp, Constant Contact or Salesforce.

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 works

From 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.

Agent-first

Your agent checks the list before it sends

A REST API with an OpenAPI spec, our MCP server for Claude, Cursor and any MCP client, and send-guard, built with our partner AskEleven. Every result says why an address was kept or removed.

API and MCP for agents

Inbound

Most businesses receive cold email, not send it

inbound-guard scores each incoming message as cold outreach and shows the signs: sequencing tools, look-alike domains registered last month, the third “just bumping this”. Open source and free.

Keep cold email out

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.
