Email verification for B2B sales teams

B2B sales teams verify CRM and prospecting exports before reps start a sequence, so bounces do not build up on the company domain that also carries customer email. Export contacts to CSV, verify, and re-import the status. Pro is $39 a month, Starter is $9 a month for 2,500 checks, and the first 100 checks are free.

A sales team shares one sending domain, and every rep's bounce count lands on it. One rep working a stale territory can lower inbox placement for the whole team, including the account managers writing to paying customers.

The CRM is where the decay is hidden: contact records are rarely deleted, so a contact who left a company two years ago is still sitting in a sequence-ready list.

SimpleVerifier facts: prices, packs and limits

What it is
Email verification with a real SMTP mailbox check: each address comes back valid, risky or invalid with a reason. Includes an email finder on Pro and up.
Price per check
Starter $9/mo for 2,500 ($3.60 per 1,000); Pro $39/mo, 100,000 a month at full speed ($0.39 per 1,000 when used), then slower, never cut off. Business $99/mo with 300,000 at full speed; Agency $249/mo with 750,000 at full speed.
One-time packs
10,000 for $15 ($1.50 per 1,000); 25,000 for $29 ($1.16 per 1,000); 50,000 for $49 ($0.98 per 1,000); 100,000 for $79 ($0.79 per 1,000); 250,000 for $169 ($0.68 per 1,000). Credits never expire, run at standard speed, CSV verification only (no API or finder).
Free checks
First 100 email checks free with a Google sign-in, no card, once per account. Single checks on the free email checker need no account.
Billing
Monthly subscription, cancel anytime (yearly billing optional). One-time packs are listed above. Starter allowances reset monthly and do not roll over.
Speed today
Capacity is shared by every customer: plan on about 13,000 mailbox checks a day in the standard lane (more when the queue is quiet). Bad syntax, dead domains and disposable addresses return at once; a list of 100,000 takes days, not hours, and each job shows its estimated finish time.
Catch-all handling
Catch-all (accept-all) addresses stay risky, never valid, and are graded higher, medium or lower likelihood with the reasons. Anything a mail server does not confirm is risky.
API and MCP
REST API on Pro, Business and Agency (Pro includes 10,000 calls a month, then $1.50 per 1,000). Remote MCP server with 6 tools for Claude, ChatGPT, Cursor and VS Code. No API on Starter.
Integrations
Connects to Instantly, Smartlead, HubSpot and Mailchimp by API key: verifies a campaign or list and tags each contact with its result. CSV in and out for any other tool.
Phone
Free phone format checks (country, type range). Live carrier and line-type lookups come with Pro + Phone at $49.99/mo (5,000 a month). It never says a number is in service.
Privacy and GDPR
Data processing agreement countersigned on request (/dpa). Results files deleted 7 days after a list is submitted; confirmed results cached by address for 14 days. Lists are not used for marketing, sold or shared. Verification runs on a US server. No GDPR certification is claimed.
What it does not do
No sending, warmup or inbox placement tests. No published accuracy benchmark against other verifiers. Catch-all domains, Yahoo and AOL cannot be confirmed, and Outlook.com and Hotmail mailboxes are not probed while Microsoft refuses checks from our server's network: all of these come back risky, never valid.

Test it on a real address first

Type any address. It gets the same check the paid plans run: syntax, the domain’s mail servers and, where the provider allows it, a live mailbox check. Nothing is sent to the address.

Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.

Have a list? Sign in with Google and the first 100 addresses are checked free, with results to download. No card.

By continuing you agree to our Terms and Privacy Policy.

How a CRM fills with dead contacts

Contacts enter the CRM from conference scans, enrichment tools, inbound forms and reps' own typing. Each source has a different error rate, and nothing in the CRM re-checks a record once it is created.

Job changes are the biggest source of decay. When someone leaves, their company mailbox is usually closed, and the first sign you get is a hard bounce from your own domain.

Typos from rep-entered records, such as gmial.com or a missing letter in a domain, never reach the person at all and never reach a bounce report until a send is attempted.

What verification adds for a sales team

Each contact is returned valid, risky or invalid with a reason. Reps can sort by it: valid contacts get the sequence, risky ones at accept-all companies get a call or a LinkedIn touch first, invalid contacts get flagged for research instead of an email.

Managers get a number they can act on: the share of a territory's contacts that are invalid, which says whether the data source or the rep's hygiene is the problem.

Every result is valid, risky or invalid with a plain reason beside it, such as "Mailbox exists", "Mailbox not found", "Accepts all addresses", "Disposable address", "No mail server", "Server would not confirm" or "Provider hides mailbox status".

Export, verify, re-import

Export the contacts you plan to sequence from the CRM as CSV, including the record ID and the email column. Upload the file, download the results, and join them back on the record ID.

Re-import with a single custom field such as email_status holding valid, risky or invalid, then build the sequence enrolment view on email_status = valid. Re-run the export quarterly for contacts you have not touched.

Which plan fits, and what it costs

Starter is $9 a month for 2,500 checks; unused checks don't roll over. Pro is $39 a month with no per-email credits: never cut off: the first 100,000 emails a month run at full speed, then big lists run slower. B2B sales teams usually start on Starter for a single list and move to Pro once lists arrive every month. The first 100 checks are free with a Google sign-in, no card, on the same engine the paid plans use.

A CSV holds up to 100,000 rows. If you work from an AI assistant, the same checks are available over MCP at https://simpleverifier.com/api/mcp, and Pro includes 10,000 calls a month included, then $1.50 per 1,000 for connecting a form or app.

How long it takes

Mailbox checks are paced, because mail servers slow down or block verifiers that probe too fast, and the daily check capacity is shared between customers. Addresses that need no mailbox check, such as broken syntax, dead domains and disposable addresses, come back at once. The rest run in a queue, and the job card shows an estimated finish time. Start the check before the send is due, and you can close the tab: the results wait in your history.
