Email verification for mortgage brokers
Mortgage brokers rely on email for rate alerts, document requests and past-client follow-up, so an address that bounces is a lost deal or a stalled file. Verify purchased leads on arrival and past-client lists before campaigns. Starter is $9 a month for 2,500 checks, Pro is $39 a month, and the first 100 checks are free.
A broker's pipeline has two very different lists. Fresh leads from vendors and ads are worth the most in the first hour and decay fast, and past clients are worth a refinance conversation years later, if the address still works.
Both fail the same way: nothing tells you an address is dead until a message bounces.
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.
Speed and decay in a loan pipeline
Lead vendors sell volume, and a share of any batch carries typos or throwaway addresses. Speed to contact is the competitive edge, so a call or email to a bad address burns the first-hour advantage.
Past-client lists are long-dormant: a borrower from 2021 may have changed jobs, moved, or dropped an old provider address. A rate-drop campaign is exactly when you need the list to be right.
Document requests are sent from the broker's own domain. Repeated bounces on that domain make it more likely that the one message a borrower must see goes to spam.
Verification in a loan workflow
Check new leads by API or by a batch CSV before the autoresponder runs, and route invalid ones to a call-only queue. For past clients, run the whole book once a year.
Role and shared addresses such as a family inbox are labelled, so you can decide whether a joint borrower needs their own contact.
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".
Before a rate-drop campaign
Export past clients from the CRM with the email and loan-closed date. Verify the file, send the rate alert to valid rows, and ask the invalid ones for a current address on the next phone touch.
Re-import the result and set a reminder for the same export next year.
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. Mortgage brokers and loan officers 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
- Does this handle sensitive borrower data?
- Upload only what you need, which can be a CSV with just the email column. Check your own compliance obligations first; SimpleVerifier verifies addresses and is not a compliance service.
- Can I check leads as they arrive?
- Yes, through the API, which Pro includes. The CSV route is enough for weekly batches.
- 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.
