Get an address from a website
No email in the file? Derive it from the domain, for every row, without a credit meter running.
- Works on every row with a company website
- Tick common prefixes or add your own
- No credits, no lookup fees
The website is there. The email is not.
A column full of domains
Scraper exports and directory lists are generous with websites and stingy with email addresses. You end up with a column full of domains and a column full of blanks.
- www. and paths are stripped, only the domain is kept
- Links to social media pages are left alone
Every row, in one pass
Most small and mid sized companies use the same handful of general addresses: info@, hello@, sales@, contact@, support@. Riftjaw takes the website you already have and builds those addresses for you, on every row, in one pass.
- Tick several prefixes at once
- Add prefixes that fit your market, like orders@ or planning@
No longer a dead end
A list of 600 roofing firms with websites but no addresses stops being a dead end. Every week that list sits unused, some of those companies pick a supplier without ever hearing from you.
How it runs
Deriving sits in the column step of an import, right under the matching. Start one with the file that has the websites.
- Pick the website column. Match it to the Website field. If the file has several URL columns, you choose which one is the company site.
- Tick the prefixes. Choose from info@, hello@, sales@, contact@, help@ and support@, or add your own. Each ticked prefix becomes an address on the row.
- See the count first. Before anything is saved you see how many rows get an address, how many already have one, how many only link to social media and how many have no website.
- Check and push. Rows that already have an email keep it. The existing address always wins over a derived one.
Be clear about what this is
A derived address is a guess based on common patterns. It is not verified. Riftjaw does not check whether the mailbox exists, and it never pretends it did. What it does is keep the guesses apart, so you always know which addresses came from a real source and which ones did not.
- Every derived address can get the tag Guessed email
- Every record keeps its source and the date it was added
- A derived address never replaces one from your file
Derived address or real address
Both are useful. They are just not the same thing, and Riftjaw keeps them apart.
| Derived from domain | From your source file | |
|---|---|---|
| Where it comes from | Domain plus a prefix you chose | The list or page you imported |
| Verified | No | Depends on the source |
| Overwrites the other | No | Yes |
| Cost per address | Nothing | Nothing |
| Marked on the record | Tag Guessed email | Source and date |
Some derived addresses will bounce. Send in small batches and watch the first ones. The guide on deriving emails explains what to expect.
Why people use this instead of an email finder
Every lookup costs a credit, even when it finds nothing.
Deriving costs nothing. Run it on ten rows or ten thousand.
Finders return personal addresses you may not want to use for a first cold mail.
General addresses like info@ reach the company, not a named person. That is often the more careful first step. See the GDPR guide.
Finders often come back empty on small local firms.
Deriving only needs the website, so a firm with no named person online still gets an address.
You forget which addresses came from where.
Derived addresses carry the tag Guessed email on the record, next to source and date.
Questions people ask
No. They are guesses based on common patterns. Riftjaw does not check if the mailbox exists.
The existing email always wins. Deriving only fills rows where the email is empty.
info@, hello@, sales@, contact@, help@ and support@, plus any prefix you add yourself, like orders@.
No. There are no credits in Riftjaw, on any plan.
Yes, some will. Send small batches first and keep an eye on the result. Campaigns send in batches by default.
