GDPR worries when you sell to window cleaners
Could you show where each contact came from if someone asked? Here is how people who sell to window cleaners fix it.

Could you show where each contact came from if someone asked?
Rules such as the GDPR expect you to know where personal data came from and to respect objections. With loose spreadsheets that is hard to prove.
It hits harder when you sell to window cleaners. Window cleaners are usually sole traders or small teams running regular rounds of homes and shops. Their business lives on repeat customers, so they buy things that help them collect payments, plan rounds and keep water fed pole kit running.
Uncertainty makes you hold back on outreach, or take risks you would rather avoid. A request to see or delete data becomes a scramble.
Source, date and opt-out on every record.
Riftjaw keeps the source and date on every record and has an opt-out register. Unsubscribed contacts are never mailed again, and you can export or delete a contact on request. Data stays on your account's own server; this is not legal advice, but it gives you the records to work with.
- Fields that fit window cleaners, such as water fed pole
- Email prefixes that fit, like info@, hello@ and enquiries@
- Status, tags and a segment on every record

Fixing it in Riftjaw
- Import with a source. Every imported record keeps where and when it came in.
- Respect opt-outs. Unsubscribes land in the opt-out register and are skipped in every campaign.
- Handle requests. Export or delete a contact when someone asks.

Other walls when prospecting window cleaners
Many window cleaners have no website, only a phone number and a social page.
Import them with the phone number and a tag, and remove the ones without a site from the segment you mail.
Lists from local directories contain the same trader under different names.
Choose phone or website as the key field so Riftjaw flags duplicates before you publish.
Short, friendly messages work, but writing each one by hand takes hours.
Write one campaign with placeholders and fallbacks and send it in gentle batches of 10.
Fields worth recording for window cleaners
Record these and you can split the list later, write sharper mails and see who fits your offer.
| 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. |
| Water fed pole | Shows whether they need pure water systems and spare parts. |
| Commercial rounds | Shops and offices mean larger, more regular work. |
| Extra services | Gutter and fascia cleaning need extra equipment. |
| Payment method | Tells you whether they still collect cash at the door. |
Questions people ask
For those with a website and business email, yes. Keep phone numbers in the same record, tag contacts you have called, and use email where you have an address.
Yes. Add a Commercial rounds field, fill it during research and save a filter on it.
If your file has an email column, that wins. If it only has websites, tick the prefixes you want, such as info@, hello@ and enquiries@, 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.
