Email Verification for Home Service Businesses: Cleaning a Jobber or Housecall Pro Customer List

A home services customer list needs cleaning before every seasonal send. Emails are collected at the door or on a tech's phone, so they come in with typos, placeholders like none@none.com, and the office's own address typed in to get past a required field. Export the list from Jobber or Housecall Pro, strip the junk, merge the duplicates, and verify what's left before the tune-up promo or review request goes out.

Getting the list out

Platform	Path	Notes
Jobber	Clients > More Actions > Export Clients > CSV	Admins only, select plans. Emailed to you; larger lists arrive as several files of about 1,500 rows. Filtering by tags keeps only clients with every selected tag.
Housecall Pro	Customers > Actions > Export	Admins only. Emailed from notifications@housecallpro.com.

For Jobber exports split across several files, combine them before cleaning with CSV merge.

Step by step

1. Pull the email column out cleanly. Upload the export to CRM export to email list; it finds the email column and gives one row per address.
2. Remove placeholders. Look for none@, noemail@, na@, test@, customer@ and your own company domain. Sort the column and they cluster at the top of each domain.
3. Remove duplicates. One household often has two records (a new property, a second job). Remove duplicate emails handles case and spacing differences.
4. Fix obvious typos such as gmial.com or yahooo.com. The email typo corrector suggests the fix; check the suggestion against the customer record.
5. Verify the rest on the verify page. Remove invalid results from the send, and update the email field on those customers in Jobber or Housecall Pro so the next export is cleaner.
6. Send to risky and unknown results last, in a small batch, and watch bounces.

What verification won't settle

Property managers and commercial accounts often use company domains set up as catch-alls, which accept every address, so a single mailbox can't be confirmed. Many homeowners use outlook.com or hotmail.com, and Microsoft's consumer mailboxes don't answer single-mailbox checks reliably. Both come back risky or unknown. They're usually real customers; don't delete them, just send them after the confirmed group. Accept-all vs unknown explains how to treat each.

Fix it at the source

Ask the tech or the office to read the email back to the customer, and turn on any confirmation the booking form offers. If you take online bookings through a form on your site, a check at the form stops the typo before it reaches the job. Catching email typos at signup shows the common ones. If you also send text reminders, the phone numbers need the same treatment; see clean CRM phone numbers.
