We try to send emails to customers and some recipients get emails with [Preview] in the subject.
To explain the background:
We send a test email in preview mode and this works fine and that
has [Preview] in the title as usual.
Then we send this email to a list that has one recipient (a different email address than we used for the test in preview mode).
This email is received with the [Preview] prefix in the subject.
The mailing setup has no accidental [Preview] in there subject, the [Preview] must get inserted upon sending.
We sent the same email (duplicate) to another list, also with one (different) recipient and that gets received without [Preview] in the subject.
We have the license valid until 20/11/24
NS version 13.0.6
Should not be related to license at all, sounds more like something thinks that a preview is rendering.
Your saying that ”some” emails get this, not all? I’m wondering if you would send to e.g. 4-6 different recipients are you saying that only some emails get this prefix?
I sent to each list separately.
I have now sent the same email to both lists at the same time and one came with [Preview], and another came without. So same effect.
Not sure I follow, how would you be able to send the same campaign "separately?" That would mean sending it twice? After the first time you've sent it it will change state to "sent" and you should not be able to send the same campaign again.
I think I need a step by step guide on how to re-produce this issue. Please provide exact details, exakt email (you could just change to some fake but so that I understand if the addresses are the same or not) and screenshots so that I understand.
How are you sending your emails? Over SMTP? Have you tried other transports? E.g. the pickup directory or similar to rule out any issues with this?
If you prefer, feel free to email me at markus [at sign here] enkelmedia.se if you feel more comfortable sharing details over email.
Hi Markus,
Yes, I explained in my initial post that we duplicated the campaign and sent it to another list. Also, the recipient addresses are different in each list.
Sorry if it was unclear in my initial post.
I am not sure how to reproduce the issue, we're not doing anything different than before. Our recipient lists and the NS service have been the same already for a few months and haven't changed.
No need to apologize, after reading your initial post again you did indeed mention that. I should say sorry :)
I've tried to reproduce the problem and I've also look at the code. The only place where we append "[Preview]" is on a newly created MailMessage that is never reused, we're not touching the underlying Campaign-entity, only the MailMessage that get's created during the sending process.
Given that I can't reproduce it and that I can't see how this is happening with the MailMessage before it's sent I'm starting to wonder if it could be something that happens after the MailMessage is rendered and sent of to the SmtpClient for sending.
I need to know more about how you are testing this.
How are you sending these tests? Are you using a real SMTP server? SMTP Pickup? Any external service? Which? Did you try different methods of sending?
Where do you see the e-mails? In your Outlook inbox? Which software?
Are all three recipient addresses different? The test email, the one email in the first list and the one email in the 2nd list?
Can you share screenshots of the rendered emails? (ok to blur stuff that you don't want to expose)
Do you have any kind of custom code in regards to Newsletter Studio? Custom Email Service Provider, custom Render Tasks etc?
Maybe there is some kind of thing with Gmail, since the body is more or less exactly the same and that they are sent very close to each other? Maybe it's trying to be smart about this and filter out "duplicates" or something - I know it's a long shot.
I would recommend that you try to send to multiple different inboxes with different technologies to rule out any issues around this.
Please, reach out over e-mail and I'll ensure to help you.

Hi!
This sounds very strange indeed.
Should not be related to license at all, sounds more like something thinks that a preview is rendering.
Your saying that ”some” emails get this, not all? I’m wondering if you would send to e.g. 4-6 different recipients are you saying that only some emails get this prefix?
What version of the package are you using?
Added the version in my original post: 13.0.6
Yes, two different lists (see my points 2 & 3 above), one gets [Preview], another does not. Both with only one (different) recipient.
Thanks for the details.
I'll try to reproduce this right away. Some more questions:

Hi again!
Just tried to reproduce on 13.0.6 without success,
Here is a screen recording https://www.dropbox.com/scl/fi/uzh2kinmg3ssdhnmwvgoi/ns-send-issue.mp4?rlkey=1agfol75lkx3mynj8n4pei85q&dl=0
Could you elaborate on your issue, are you using the exact same steps? What' the difference?
Thank you!
I sent to each list separately. I have now sent the same email to both lists at the same time and one came with [Preview], and another came without. So same effect.

Hi Markus, I'll send you an email to discuss the details.
Though first, I will do more tests with multiple recipients on one list to compare all emails received. And I'll do a test using SMTP Pickup.
All emails are received in a Gmail inbox. The email body looks correct.
Hi!
Thanks for letting me know.

All the best!
Hi Markus, We have run additional tests, including sending to a list with multiple recipients and the issue stopped appearing.
I honestly do not know what it was but again, thanks for such a quick reaction and support!
