Cannot target a niche when you sell to plumbers
Can you pull up only the dentists in one region in a few clicks? Here is how people who sell to plumbers fix it.

Can you pull up only the dentists in one region in a few clicks?
A long list with every kind of business makes focused outreach hard. Filtering spreadsheets again for each campaign is tedious.
It hits harder when you sell to plumbers. Most plumbing firms are owner-run with a few engineers and a van each, so the person you want is often the one under a sink when you call. The owner decides on almost everything, from software to suppliers, and tends to buy when something saves time on quoting, invoicing or finding the next job.
You send the same message to very different businesses and it fits none of them well. Focused offers never get sent.
Named segments, ready for a campaign.
In Riftjaw every contact you add and every import goes into a segment with its own name, like Dentists Leeds. A campaign asks which segment to reach first. Next to segments there are saved filters, rules such as city contains Leeds, which a campaign can reach too.
- Fields that fit plumbers, such as service area
- Email prefixes that fit, like info@, office@, enquiries@ and hello@
- Status, tags and a segment on every record

How to fix it in Riftjaw
- Name the segment. Create it on the spot when you import the list, or pick one you already have.
- Add or remove in bulk. Select contacts in the list and add them to the segment or remove them.
- Use it as audience. Pick the segment when you start a campaign.

Other walls when prospecting plumbers
Plumber listings are spread over directories, maps and review sites, and each one exports in a different shape.
Import every CSV or Excel file into one lead file, map the columns once and let Riftjaw flag duplicates before anything is added.
Many small plumbing firms only list a phone number and a website, with no email address.
Email from domain builds likely addresses such as info@ and office@ from the website, marked as guesses so you know what is unverified.
Owners rarely reply first time because they are on jobs all day.
Set a status per contact and a tag like already called, so a follow-up a week later goes only to the people who have not answered yet.
Fields worth recording for plumbers
Any column in your import can become a field. These are the ones worth keeping for plumbers.
| Field | Why it helps |
|---|---|
| Company name | The key field. Duplicates are checked on it or on the website. |
| Website | Needed to derive an email when the export has none. |
| Service area | Where they work, so you can split the list by town or region. |
| Emergency callouts | Firms that offer out of hours work often care about call handling and dispatch tools. |
| Gas work | Whether they also do boilers and heating changes what they buy and who they buy it from. |
| Team size | A sole trader and a firm with ten engineers need a different pitch. |
| Website quality | A weak or missing site is a clear opening for web and search agencies. |
Questions people ask
Collect listings from public directories or a scraper export, then import the file into Riftjaw and map the columns. Add a Service area field so you can save a filter for each town and send to it separately.
Yes. Add a field or a tag such as gas work and fill it during import or by hand. A saved filter on that field gives you a separate list for heating related offers.
If your file has an email column, that wins. If it only has websites, tick the prefixes you want, such as info@, office@, enquiries@ and hello@, and Riftjaw derives addresses from each domain. Derived addresses are good guesses, not verified, so start with small batches.
Yes. The Free plan runs the whole pipeline on one list with small campaigns, and you do not need a credit card. Move to Pro when you want more lists, segments and bigger campaigns.
