PingValid

PingValid is an email validation service. This connector lets your assistant check whether an email address can receive mail, one address at a time or as a list.

What it checks: syntax, domain and DNS, MX records, disposable domains, role accounts (such as abuse@ or postmaster@), an SMTP probe that asks the receiving server whether it accepts the mailbox without sending a message, and, on the Deep tier, catch-all detection. The Deep tier needs a paid plan or a top-up.

What you get back: one of four verdicts (valid, risky, invalid, unknown), a risk score from 0 to 100, and the result of each check, so you can see why an address was flagged.

Tools:

• Validate email: check one address and get the verdict, risk score and evidence. Uses credits.
• Submit bulk job: validate a list of up to 1,000 addresses in one job. This starts a job in your PingValid account and uses credits.
• Get job status: see how far a bulk job has progressed. Free.
• Get job results: read the per-address results of a finished job, optionally filtered by verdict.
• Explain verdict: get a plain-language explanation of a result. Free.

What you need: a PingValid account. The Free plan includes 100 validations a month on the Quick and Standard tiers and needs no card. Connect with OAuth; there is nothing to install.

Cost: the connector uses the same credits as PingValid's web app and API. One validation uses 1 credit (2 on the Deep tier). Repeat checks served from cache are free on the Quick and Standard tiers. Unknown verdicts are not charged. Pricing is published at pingvalid.com/pricing.

What it does not do: validation tells you whether an address can receive mail at the time of the check. It does not send email and does not guarantee inbox placement.
