Catch-all report
Is sendgrid.com a catch-all domain?
This report shows the mail configuration for sendgrid.com and runs a live catch-all probe. A catch-all (accept-all) domain accepts mail for every address, which makes verifying individual sendgrid.com mailboxes less certain.
Test a domain for catch-all
This opens one SMTP conversation with the domain's mail server and asks whether a random mailbox is accepted. Many networks block outbound port 25, so a single check can be inconclusive.
Catch-all domains need smarter verification
On a catch-all domain, the server accepts everything, so SMTP alone cannot tell a real mailbox from a typo. Verifly combines multiple signals and flags catch-all addresses so you can decide how to send.

What catch-all means for sendgrid.com
When a domain is catch-all, its server returns a 250 OK for any recipient — ceo@sendgrid.com, sales@sendgrid.com, or pure gibberish alike. That is convenient for the domain owner (typos still arrive) but it removes the signal a verifier relies on: acceptance no longer proves the mailbox exists.
The right way to treat a catch-all sendgrid.com address is as a middle tier — riskier than a confirmed mailbox, safer than a hard-invalid or disposable one. Verifly returns a dedicated is_catch_all flag so you can decide how aggressively to send instead of guessing.
FAQ — sendgrid.com catch-all & verification
- Is sendgrid.com a catch-all domain?
- A domain is catch-all when its mail server accepts mail for any address, including ones that do not exist. Run the live probe above to test sendgrid.com right now — it opens one SMTP conversation and asks the server whether a random, non-existent mailbox is accepted.
- What are the MX records for sendgrid.com?
- sendgrid.com routes mail through: smtp.google.com. This indicates the domain uses Google Workspace (Gmail).
- Why does catch-all matter when verifying sendgrid.com addresses?
- On a catch-all domain an SMTP accept does not prove a specific mailbox exists — the server says yes to everything. So a verifier cannot promote a catch-all address to "valid" on acceptance alone; it should flag it separately, which Verifly does.
