Yes. You can verify any @Alice.de address in real time with a direct SMTP handshake that provides 99.7% accuracy. Alice.de is operated by Alice DSL, runs 4 mail servers, enforces 1 of 3 authentication standards, and is currently responding to SMTP.
Every check returns one of three clear outcomes so you know exactly what to do with the address.
The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
alice.de publishes 4 MX records. The primary mail exchanger is mx1c52.megamailservers.eu, hosted by megamailservers.eu, and it is currently reachable and answering SMTP. Mail is routed through these servers in priority order, lowest number first.
| Priority | Hostname | IP | Status |
|---|---|---|---|
| 10 | mx1c52.megamailservers.eu | 91.136.8.194 | Reachable |
| 100 | mx2c52.megamailservers.eu | 91.136.8.195 | Reachable |
| 110 | mx3c52.megamailservers.eu | 91.136.8.196 | Reachable |
| 120 | mx4c52.megamailservers.eu | 91.136.8.197 | Reachable |
220 mail99c50.megamailservers.eu ESMTP Sendmail 8.14.9/8.13.1; Tue, 2 Jun 2026 10:11:14 +0000Yes. alice.de is a valid email domain, operated by Alice DSL. Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.
A live SMTP handshake connects to Alice.de's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.
Free inboxes get abandoned constantly. Verification drops the dead alice.de mailboxes before you mail them.
Mistyped alice.de addresses fail a real SMTP check, so they never turn into a hard bounce.
A clean list keeps your bounce rate low, and a low bounce rate is what protects inbox placement on a big send.
Mailing only live alice.de addresses raises every rate that matters: opens, clicks, and replies.
