Some Campaign Emails Not Delivered

[roblaus]

For quite some time i suspected that something was wrong with the delivery of campaign emails, now I can prove it. For no apparent reasons some emails are marked as sent but never arrive.

We ran a few checks with somebody who didn't get a mail: receiving and sending domain are fine, no blacklist or anything, no spam filter. Proof: emails from the SAME campaign reached somebody else in the same domain without problems. Proof2: Emails to the same recipient sent from a different campaign arrived.

The same behaviour with a customer of mine - I never receive their test campaigns although Sugar says it has been sent (spam and blacklist checked), all other mails from them arrive.

This is very disturbing because it may be going on forever already - who the heck checks whether an email campaign was received by everybody? Plus it is very hard if not impossible to trace outgoing emails.

Hello Robert,

What version are you using? Have the emails gone to the junk box? what type of email are the recipients using? We noticed that Outlook 2007 is more restrictive on the emails that come through than Outlook 2003. When testing internal campaigns, one of our employees who is on Outlook 2003 receives campaign emails with no problems, while on Outlook 2007, the email does not come through. After much testing, it is usually due to a word or specific wording that Outlook 2007 does not like and blocks.

Besides this, we have not noticed any unusual issues with the campaigns (although i have not had the chance to work much with 5.2 yet).

Hi,

My first thought was of course spam but we could definitely exclude a spam filter. The whole thing came up because I sent our private Christmas mail through Sugar and there are

a. only about 70 recipients and
b everybody opens the mail

Since only 35 people opened the mail we started calling them and it t turned out that some indeed did not receive anything. AS I said, I already suspected smthg like that but I couldn't put my finger on it. As we speak I am running a test.
And no, its 51c
