Email verification for gyms and fitness studios
A gym's email list is mostly trial leads, class bookers and lapsed members, entered at a front desk or on a phone, so typos and old addresses are common. Verify the member export before a promotion or win-back send. Starter is $9 a month for 2,500 checks, Pro is $39 a month, and the first 100 checks are free.
Most of a studio's addresses were typed in a hurry: at the desk during a tour, on a phone at the class booking screen, on a one-week-pass form. The cost of a typo is a member who never sees the freeze notice or the win-back offer.
The list is also seasonal. January and September bring a wave of sign-ups, and most of the lapsed list comes from those same waves.
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.
Why a member list degrades
Trial and free-pass forms get the most fake and mistyped addresses, because people want the pass but not the emails. A fake address gives you a lead that looks real in the CRM.
Lapsed members are the valuable segment for win-back offers and the stalest one. People who stopped coming a year ago often changed jobs or inboxes since.
A booking system that sends class reminders from your domain suffers when a share of those reminders bounce, because the same domain carries payment and renewal messages.
What to check and what to do with it
Verify the lapsed-member export before a win-back campaign, and the trial list before the follow-up sequence. Disposable addresses are flagged, which usually means someone who only wanted the free pass.
Invalid addresses on active members are a front-desk task: ask for a correct address at the next check-in instead of letting renewal notices bounce.
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".
A seasonal clean-up routine
Two weeks before a January or September push, export active, trial and lapsed members from the studio software as three CSVs. Verify each and tag the invalid active members for the front desk.
Send the campaign to valid rows only, and re-import the status so next season starts from a cleaner base.
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. Gyms and fitness studios 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.
Common questions
- Should I email lapsed members at all?
- That is your call and depends on your consent records. Verification only tells you which addresses exist; it does not decide whether you may email them.
- What about members who gave a phone number only?
- Email checks need an email. The Pro plus phone plan adds phone checks if you also text members.
- How do I try it first?
- The first 100 checks are free with a Google sign-in, no card, on the same engine the paid plans use.
- What does it cost?
- Starter is $9 a month for 2,500 checks, or Pro at $39 a month: never cut off: the first 100,000 emails a month run at full speed, then big lists run slower. Plans are monthly or yearly and cancel from your account.
