It could also be caused by a blacklisted server. Errors like this are generally encountered when there is an issue on the recipient server, or the intended recipient does not exist on the remote server. The “typo” domain name exists on the Internet, but because it doesn’t usually receive mail, nobody notices or fixes the “temporary” problem its mail server has.įive-day-old bounces are a common problem if your email address was compromised and used to send spam that ends up at non-working email servers. So, you sent an email and it was returned or bounced back to you with a message like: Mail delivery failed: returning message to sender. For example, if you send a message to an address instead of (note the missing letter in “gmail”), it might take a while to bounce. But it’s rare for a real address to have failing servers for 5 straight days: if a real domain name has technical problems, someone will usually notice it and fix it before that.īecause of that, these kinds of bounces usually happen only when messages are sent to invalid servers that nobody is monitoring, particularly ones with “typos” in the domain name. When this happens, our servers will keep trying for the Internet standard of up to 5 days before finally sending a “bounce” notice that the message was undeliverable even after retrying.Īll of this is controlled by the receiving server and the response it sends, so there isn’t anything that can be done to speed up or change this process for individual messages. However, there are some cases where the receiving mail server has an extended period of downtime, or always indicates that it’s having a “temporary” failure.
EMAIL BOUNCE BACK MESSAGE OFFLINE
(It wouldn’t make sense to “bounce” a message as undeliverable if the receiving mail server is just offline for a few minutes.)
This is common - and in most cases, the message is successfully delivered with a short delay.
2) Avoid sending messages to recipients after many months of zero contacts. Please follow the below steps: 1) Only send the email messages that recipients could reasonably expect to receive. But sometimes, the receiving email server indicates it’s having a temporary problem - that it’s unable to accept mail now, but that it wants our servers to keep trying, because it should be possible to deliver it in the future.įor example, this happens if the receiving mail server is undergoing scheduled maintenance, or experiencing temporary downtime or another technical issue that should be resolved soon. If you receive this type of bounce back message from MailChannels, the email recipients frequently complain about your legitimate messages. Most of the time, you’ll see any undeliverable “bounce” as soon as you send a message. A hard bounce means that the email address is permanently closed and not receiving electronic mail. A bounced email can be either a hard bounce or a soft bounce. When an email bounces, it has for some reason not reached the intended destination. Customers occasionally ask why they received a undeliverable “bounce” message for an email they sent days before. A bounced email, or bounce, is an email message that gets rejected by a mail server.
