Terra email checker: does this terra.com.br mailbox exist?

In short: Asks Terra's own mail server whether a terra.com.br mailbox exists, without sending anything, after syntax, domain, disposable and role checks. Limit: A valid result shows Terra accepted the mailbox today, not that anyone reads it.

To check if a terra.com.br address exists, enter it here. The checker asks Terra's mail server about the mailbox at RCPT TO, then disconnects before any message is sent. Terra rejected made-up addresses with 550 5.7.0 recipient rejected on 23 October and 8 November 2026, so a missing mailbox comes back invalid and an accepted one valid.

Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing

Tuned for terra.com.br. Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.

What can a check confirm at Terra, and what did we measure there? Can you verify a Terra address?

How do I check a whole list of Terra addresses?

  1. Export the list as a CSV or copy the email column; Terra rows and every other domain can go in together.
  2. Upload or paste it at /verify. The first 100 email checks are free with a Google sign-in, no card.
  3. For every list after that, Pro includes unlimited email verification. Fair use: the first 100,000 checks a month at full speed, then slower, never cut off.

How do I check a Terra email address?

  1. Type or paste one address, such as [email protected].
  2. Press Check. The tool checks the syntax and domain, asks Terra's server about a random address that can't exist, then about yours, and disconnects before anything is sent.
  3. Read the verdict: valid means Terra accepted the mailbox and rejected the made-up one, invalid means it rejected the recipient, risky means the check didn't get a clear answer.
  4. If it comes back risky, check again later: with Terra that is usually a cut-short check, not a bad address.

Example

You enter
One address: [email protected].
You get
Valid when Terra accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers 550 5.7.0 recipient rejected; risky only when the check gets no clear answer.
Limits
Five checks a minute per IP address, one address at a time, no account needed.

How do I check if a terra.com.br address exists without emailing it?

Ask Terra's mail server instead of the mailbox. On 8 November 2026 terra.com.br published one MX host, mx.terra.com.br. On 23 October 2026 it answered a made-up address at RCPT TO with 550 5.7.0 recipient rejected, and a fresh made-up address got 550 5.7.0 recipient rejected - TIDR502 through this checker on 8 November.

Terra uses the policy code 5.7.0 rather than 5.1.1, but the rejection comes at RCPT TO for a recipient that can't exist, so a missing Terra mailbox comes back invalid ("Mailbox not found") and an accepted one valid. The Terra provider page has the full DNS snapshot.

Why do terra.com.br addresses go dead?

Terra Mail is a subscriber service. Clause 2.9.1 of the Terra Mail conditions says that once a subscription is cancelled for any reason, all mail, contacts and extra accounts are removed from Terra's servers straight away and can't be recovered. Clause 3.3 says a username already chosen by one subscriber can't be taken by someone else.

So a Brazilian contact who left Terra may now have no mailbox at all. Re-check older lists before a campaign, for example with the bulk verifier, and remove the rows that come back invalid. For uol.com.br and bol.com.br, use the UOL email checker.

What can this checker confirm at Terra?

Each row is something the check runs on a Terra address, and the result you can get from it.

CheckCan we confirm it?Result when it fails
Syntax (the address is written correctly)YesInvalid
Domain and mail server (MX)YesInvalid, with a typo suggestion where one fits
Disposable or role addressYesInvalid (disposable) or risky (role)
The mailbox existsYes: Terra answers at RCPT TO (550 5.7.0 recipient rejected)Invalid, "Mailbox not found"
A temporary reply or timeoutNo answer to readRisky, worth checking again later
Someone reads the inboxNo checker canUse opens, replies or a small first send

Our checking server offered a made-up address and disconnected without sending, through this checker on 8 November 2026; earlier checks are dated in the text.

What can’t this tool tell you?

  • A valid result shows Terra accepted the mailbox today, not that anyone reads it.
  • A temporary reply or a refused connection comes back risky, not invalid.
  • Terra doesn't publish how its servers answer mailbox checks; the handling here is from our own checks, which can change.
  • One address at a time, five a minute.

Common questions

How do I check if a terra.com.br email address is valid?
Enter it here. The checker confirms the syntax and mail server, then asks Terra's server about the mailbox without sending. Terra rejects addresses that don't exist, so a missing mailbox comes back invalid.
What does 550 5.7.0 recipient rejected mean from Terra?
Terra's server refused that recipient. It uses a policy code, but at RCPT TO for an address that doesn't exist, so treat it as a hard bounce and remove the address.
What happens to a Terra mailbox when the subscription ends?
Terra's conditions say all mail, contacts and extra accounts are removed from its servers immediately after cancellation and can't be recovered.
Can someone else take an old terra.com.br username?
Terra's conditions say a username already chosen by another subscriber can't be chosen by someone else.
