How to verify a telus.net email address
Can you verify @telus.net addresses?
YesYes. @telus.net answers mailbox checks one address at a time.
Check one address
Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.
Checking a whole list? The first 100 addresses are free, with results to download. No card.
By continuing you agree to our Terms and Privacy Policy.
The checker opens an SMTP conversation with telus.net's mail server, offers a random address first to rule out a catch-all, then names your address at RCPT TO and disconnects without sending. A rejection comes back invalid ("Mailbox not found") and an acceptance valid ("Mailbox exists"). Temporary replies come back risky. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.

On 13 October 2026 the telus.net mail server aspmx.l.google.com rejected a made-up recipient at the SMTP RCPT TO step with 550 5.1.1 The email account that you tried to reach does not exist., so a mailbox check can tell a missing telus.net account from a real one.
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. See pricing

What TELUS's server says about a missing mailbox
The reply that matters is the one to RCPT TO, the step where the checking server names the recipient. TELUS answered our made-up telus.net address with 550 5.1.1 The email account that you tried to reach does not exist.. A 5xx code at that step is a permanent "no such mailbox", which is the same answer a real message would get, so SimpleVerifier marks the address invalid with the reason "Mailbox not found". A 250 at the same step means the mailbox exists and comes back valid.
Before trusting a "valid", a careful verifier also offers a random address that cannot exist. TELUS rejected ours, so telus.net is not a catch-all: a 250 for your address is a real signal. Temporary 4xx replies (421, 450, 451) are about the connection, not the mailbox, and come back risky with "Server would not confirm" rather than invalid. Hard bounce vs soft bounce explains why that split matters.
TELUS mail is hosted on Google Workspace, so the answer comes from Google's servers in the same words as for gmail.com.
Cleaning telus.net addresses on a list
Because TELUS answers honestly, telus.net is one of the domains where verification removes bounces before they happen. Drop the invalid results, keep the valid ones, and re-check the risky ones later: a temporary reply on one day often turns into a clear answer the next.
A valid result only means the mailbox exists today. Addresses on an old consumer list go stale as people stop using them, so re-verify before each large send to an aged segment; how often to verify an email list gives a schedule. Upload the CSV to the verifier and download the valid, risky and invalid rows as separate files.
Common questions
- Can you verify @telus.net addresses?
- Yes. @telus.net answers mailbox checks one address at a time. The checker opens an SMTP conversation with telus.net's mail server, offers a random address first to rule out a catch-all, then names your address at RCPT TO and disconnects without sending. A rejection comes back invalid ("Mailbox not found") and an acceptance valid ("Mailbox exists"). Temporary replies come back risky. It always checks the syntax, the domain's MX records, disposable domains and role addresses such as info@ first.
- Can I check if a telus.net address exists without emailing it?
- Yes. A verifier connects to TELUS's mail server, names the address at the RCPT TO step and disconnects before sending. On 13 October 2026 the server rejected a made-up telus.net address with "550 5.1.1 The email account that you tried to reach does not exist.", so a missing mailbox shows up as invalid and the owner receives nothing.
- What mail servers does telus.net use?
- On 13 October 2026, telus.net published these MX hosts: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com, alt4.aspmx.l.google.com. You can look them up yourself with the free MX lookup tool.
- Why did a telus.net address come back risky instead of invalid?
- Risky means the server didn't give a permanent answer during the check, usually a temporary 4xx reply or a timeout. It isn't proof the address is bad. Check it again later; TELUS gave a clear rejection for a missing mailbox when we tested it.
