Open House Sign-In Sheet Emails: Fixing Handwriting and Typo Errors Before You Follow Up
To fix an open house sign-in list, correct the domain typos first, then verify each address, and treat Mailbox not found as a visitor you need to reach another way. A sheet filled in by hand is the messiest source in a real estate database, and the follow-up is time-sensitive. The email typo corrector does the first pass, and the email verification for real estate agents page covers the rest.
The errors you will see
- Domain slips: gmial.com, gnail.com, hotmial.com, yaho.com. These are fixable.
- Missing or extra dots: firstlast@gmail.com when the person meant first.last@gmail.com. Not fixable automatically.
- Letters read wrongly from handwriting: an l for a 1, a u for a v. Not fixable automatically.
- Unfinished entries: no domain at all, which comes back as Invalid format.
Step 1: type or paste the list
Enter every address into a CSV, one per row, with name and phone. Keep the phone number, because it is your fallback for visitors whose email fails.
Step 2: correct the typos
Run the list through the typo corrector. The email typo correction guide explains which changes are safe to apply without asking.
Step 3: verify what is left
Upload the CSV on the verify page. Read the reasons:
- Mailbox not found: probably a handwriting or dot error. Call or text instead.
- No mail server and Typo domain: check the spelling again.
- Accepts all addresses: the domain takes anything, so no mailbox can be confirmed. Send, but expect some to fail.
- Yahoo, AOL or Microsoft consumer rows come back risky because those providers do not allow an honest check.
Step 4: follow up the same week
Send the thank-you with the listing details to valid rows, and use phone for the rest. A short note on a house someone just saw works better sooner. For turning those visitors into a longer drip, see cleaning an old lead list before a drip.
Keep the sheet clean next time
A tablet form with an email check built in stops the error at the door. If your form tool can call the API, a failed check can ask the visitor to retype. If not, a clear entry field and a typed list the same day still help.
What this cannot do
- It cannot work out what a visitor meant to write.
- A valid result means the mailbox exists, not that the visitor wants your follow-up.
- Microsoft consumer addresses are not probed, so they are risky by design.

Common questions
How do I fix typos in open house sign-in emails?
Run the list through an email typo corrector for domain slips like gmial.com, then verify what is left. Handwriting errors inside the name part cannot be fixed automatically.
Why are sign-in sheet emails so error-prone?
People write quickly, on a clipboard or a phone, and handwriting is read back by someone else. A missing dot or a swapped letter turns a good address into a bounce.
Can a verifier fix a misspelled mailbox name?
No. It can tell you the mailbox was not found, but it cannot guess what the person meant to write. Those visitors need another way to reach them.
When should I send the follow-up?
Soon after the open house, so verify the list the same day or the next morning. That leaves time to fix what is fixable.
What does it cost?
The first 100 checks are free with a Google sign-in, no card, which covers most open house lists.
Check your list before you send
Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
