Adding header the test message does not work..

Code:
DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/simple;
    s=gdwg2y3kokkkj5a55z2ilkup5wp5hhxx; d=amazonses.com; t=1465825122;

Without the header works in the test, but to send the campaign the dkim is invalid.

@daemon ok, so this is our finding -

While doing 'template test',

1. DKIM passes without "Feedback-ID" header
2. DKIM fails with "Feedback-ID" header

Correct ?

If that's the case, obviously SES is not handling "Feedback-ID" well on their side, that's possibly conflicting with the same header added by them. You can post this on their forum and try if that can be addressed.

Meanwhile, try dedicated IP from Sparkpost. That seems to be less pricey than SendGrid.

Without looking at the prices . What is the best ? Sparkpost ?
Seriously I have never used Sparkpost. But I could see people giving good feedback about them in the forum including @twisted1919 .

But I have used SendGrid in the past (dedicated IP plan) and they turned out to be really good to me - in terms of speed of delivery, inbox hit and analytics. Worked well for me especially for hotmail and gmail.

@VVT / @daemon - i personally used sparkpost a lot and i still am at work. But for mailwizz related things, including this forum, i am using mailgun for a while now. Sparkpost has some weird policy that they block you without any real reason, saying their spam filter decided so, which is terrible wrong having in mind they blocked even forum replies from here.

In short when you create the campaign e-mail test works, but when you send to all users error happens.

In both your signatures, the selector s=6kzodaeozq5njf23tfu7eedwaospvk4t, respectively s=6gbrjpgwjskckoa6a5zn6fwqkn67xbtw.
Mailwizz selector is s=mailer so i have no idea how that ends up there.

I've tried disabling the DKIM on amazon panel.
But always when you send up the header of the amazon (DKIM).

The funny thing is that this happens only when sending the campaign .. When I'm in TEST (Sending a test) goes right.
So I think it's something in mailwizz.
