Bulk Terra email checker: check a list of terra.com.br addresses at once
In short: Checks many terra.com.br addresses at once: duplicates and +tag repeats flagged, and 10 mailboxes asked live at Terra's server. Limit: Terra doesn't publish how its servers answer mailbox checks; the handling here is from our own checks, which can change.
A bulk Terra email checker tests many terra.com.br addresses at once. Syntax, duplicates and dead domains are flagged in your browser, then the first 10 are asked live at Terra's mail server, which rejected made-up addresses with 550 5.7.0 recipient rejected on 23 October and 8 November 2026. A missing mailbox comes back invalid, a real one valid, an unclear answer risky.

How do I check a whole list of Terra addresses?
- Export the list as a CSV or copy the email column; Terra rows and every other domain can go in together.
- Upload or paste it at /verify. Every address gets a live mailbox check, and the first 100 email checks are free with a Google sign-in, no card.
How do I check if many Terra addresses exist?
- Paste the addresses, one per line, or a CSV column of them. Addresses at other providers are checked as normal addresses and marked.
- Press Check the Terra addresses.
- Read the flagged rows: a typo domain, a duplicate, a +tag repeat of an earlier row, or a domain with no mail server.
- Download the clean list. Notes stay on it; only rows that fail a check come off.
- The first 10 go to Terra's mail server for a live answer. Sign in with Google to check the rest with 100 free email checks.
Example
- You enter
- 6 addresses:
joao.silva@terra.com.br,joao.silva+promo@terra.com.br,Joao.Silva@terra.com.br, another terra.com.br, a uol.com.br and a company address. - You get
Joao.Silva@terra.com.bris marked as a duplicate of row 1 and comes off;joao.silva+promo@terra.com.bris marked as row 1 plus a +tag and kept; the uol.com.br and company rows are marked as another provider. The live check asks Terra about the Terra rows first.- Limits
- The browser pass covers the first 5,000 rows; only domains leave your device. 10 live checks a day without an account, then the free checks with a Google sign-in.
Can you check if terra.com.br addresses exist in bulk?
Yes. Terra answered made-up addresses at RCPT TO with 550 5.7.0 recipient rejected on 23 October and again on 8 November 2026. The code is a policy code, but it comes back at RCPT TO for an address that doesn't exist, so it is treated as a missing mailbox.
The free page asks about 10 mailboxes live. A whole list goes through the bulk verifier, where Terra rows get the same check.
What happens to a Terra mailbox when the subscription ends?
Terra's general conditions say all mail, contacts and extra accounts are removed from its servers immediately after cancellation and can't be recovered.
So a Brazilian list with old terra.com.br rows can hold addresses that stopped working the day the plan ended. Check them before a campaign; for uol.com.br and bol.com.br rows use the bulk UOL and BOL checker.
What does the bulk Terra check do to my list?
The pass over the whole list runs in your browser: syntax, duplicates, typo domains and role addresses. Only the unique domains are sent out, to look up mail servers and the disposable list. Rows at terra.com.br are matched by the part after the @, so an address at any other domain is checked as a normal address and marked as another provider.
Then the first 10 addresses, Terra rows first, are asked live at the mail server without sending anything. Sign in with Google to check the rest with 100 free email checks. For one address with full notes, use the Terra checker.
What does each check catch on a Terra list?
| Check | Can we confirm it? | Result when it fails |
|---|---|---|
| Syntax and duplicates | Yes, in your browser | Bad syntax comes off; a duplicate is marked |
| Domain and mail server (MX) | Yes, from DNS | No mail server comes off |
| Disposable or role address | Yes | Disposable comes off; a role address is marked |
| The mailbox exists | Yes: Terra answers at RCPT TO (550 5.7.0 recipient rejected) | Invalid, "Mailbox not found"; an unclear reply is risky |
| Someone reads the inbox | No checker can | Use opens, replies or a small first send |

What can’t this tool tell you?
- Terra doesn't publish how its servers answer mailbox checks; the handling here is from our own checks, which can change.
- Only terra.com.br counts as a Terra row; Terra addresses in other countries are checked as normal addresses.
- A +tag repeat is marked as possibly the same inbox, not merged, because this page doesn't verify how Terra treats tags.
- The live check covers 10 addresses without an account; risky results there can mean the check was cut short, so try again later.
- Valid means the mailbox exists today, not that anyone reads it.
Common questions
- 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.
- 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.
- Is there a free bulk Terra checker?
- Yes. This page checks a whole list for syntax, duplicates, typo domains and dead domains for free, asks Terra's server about 10 mailboxes live, and gives 100 free email checks with a Google sign-in. No card.
- Will the Terra users know I checked their address?
- No. The check ends after the mail server answers about the mailbox, before any message content is sent, so nothing arrives in their inbox.
- What happens to the addresses on my list that aren't Terra?
- They are checked as normal addresses and marked as another provider. The live check asks about the Terra rows first.
Sources
A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
- Small list? Starter at $9/mo covers 2,500 emails a month, cancel anytime
Plans from $9 a month, cancel anytime, no contract. Sign in with Google and your first 100 email checks are free, no card. The free tools stay free either way.
