Email API
Everything you need to work with professional email — confirm an address is real and safe to send to, find a person’s work email from what little you already know, resolve the profile behind an address, and do all of it one-off or across a whole list. It runs on the same key, the same response envelope, and the same credit balance as the rest of Renidly.
Email is where a lot of B2B work starts and stalls. A list decays the moment it's built, outreach bounces against addresses that never existed, and a signup form hands you a name with no way to tell who's behind it. The Email API closes those gaps: verify before you send, discover the address you're missing, and turn an address back into a person and a company.
What you can do
What teams build with it
- Clean lists before you send. Strip dead, disposable, and risky addresses out of a list so your sender reputation survives the campaign.
- Fill the missing address. You have the person and the company but not the email — discover it, already confirmed as deliverable.
- Enrich inbound signups. Someone signs up with a work email; turn that single string into who they are and where they work, in real time.
- Build account contact lists. Start from a company domain and pull the people you already have on file for it.
- Gate forms and signups. Reject throwaway and undeliverable addresses at the point of entry instead of discovering them later.
How it fits the rest of Renidly
The Email API isn't a separate account or a separate key. It authenticates with the same X-renidly-apikey header (see Authentication), returns the same five-field response envelope, and draws from the same credit balance as everything else. If you already call Renidly for identity data, you're already set up for email.
