Frequently asked questions
What is an email permutator?
An email permutator generates all the common email address formats for a person at a company (first.last@, flast@, first@, etc.) so you can identify the right one.
Does this verify the emails too?
Yes. Sendburg verifies each generated address for deliverability, so you can see which are valid rather than guessing.
Is it free?
Yes, free with no signup. To skip the guessing and get the one real verified email plus a direct dial, create a free Sendburg account with 10,000 credits per month.
Why do several addresses show as valid?
Some mail servers are 'accept-all' and accept any address. Sendburg's app returns the person's actual verified email so you never send to the wrong one.
