Email validation & intelligence
RampedUp validates 90 million professional email addresses a month using a waterfall process with four independent signals. We first work directly with the recipient email server to determine whether the record is VALID, INVALID or CATCH ALL. If the record is CATCH ALL or UNKNOWN, we call the company's Active Directory for authentication. Next, we promote these records to DETERMINISTIC if we can find the email on the public web. Finally, we bundle email delivery responses into a cache of 2.8 billion signals that we call our Email Exhaust — the Exhaust is then applied to any outstanding record without a VALID response.
RampedUp provides Email Exhaust projects. The process is fast, inexpensive, and an effective way to clean lists in the tens of millions.
Email Validation — a standalone solution
RampedUp offers Email Validation as a standalone product in the platform, in two steps that keep costs down and delivery rates up.
Step 1 — Pre-Validation
Import a CSV of up to 100,000 email addresses and RampedUp evaluates them using the results from our cache of 2.8 billion signals in the Email Exhaust.
Step 2 — Real-Time Validation
SMTP negotiation — the traditional method that returns a VALID or INVALID response from the recipient server — plus Active Directory authentication, calling the company’s Active Directory API to validate the address.

Validation statuses
Grouped by how safe each status is to send.
Safe to send
Email addresses with the statuses below will deliver at a very high rate.
- Valid
- Confirmed as safe to send from the recipient’s mail server, authenticated through Active Directory, or carrying a delivery status of opened.
- Deterministic
- A catch-all address that has also been seen on a public website. Records with the Deterministic status carry a web-source URL.
- Free Mail
- An address at a consumer domain like Gmail, Yahoo or Outlook, used for business purposes. Records with the Free Mail status carry a web-source URL.
Questionable to send
Email addresses with the statuses below should be used with caution for bulk email.
- Catch All
- The mail server is configured to accept every address at the domain, so it is unknown whether the email will reach the recipient.
- Personal
- The domain is not a company domain but a consumer one like Gmail, Yahoo or Outlook. Using a personal address for business purposes will not be well received.
- Role Based
- A professional address, but not tied to a specific person. These addresses rarely respond to sales and marketing solicitations.
Do not send
Email addresses with the statuses below should not receive a bulk email; consider removing them from your database.
- Invalid
- Confirmed as unsafe to send — from the recipient server, Active Directory, or because the email has bounced recently.
- Unknown
- The recipient’s mail server and Active Directory search did not return a status. There is no history of the email delivering successfully, and it was not found online.
- Grey Listed
- High-security mail servers that deliberately withhold a status. These servers are risky to email for large sales and marketing efforts.
Four independent signals
A status is only as good as what it was derived from, so we tell you.
SMTP negotiation
The traditional validation method, returning a VALID or INVALID response from the recipient server.
Active Directory authentication
Microsoft and Google expose the ability to authenticate users of their Office and Workspace products.
Web-sourced emails
RampedUp scans tens of millions of corporate web pages each month. An address seen published on a company page is evidence in its own right.
