Tomorrow we will start with heavy TV marketing in Sweden. There will be a lot of activity on the Saga Islands and offers during this period. Take advantage of our extra exposure and get a lot more sign ups. Our TV-commercial will run until the end of the year.

Any suggestions?

Mail service filters can be a little too restrictive some times, so is better for you to set up all your domain correctly, as for now 2tunnels.com has no records on a dns query lookup, no MX, so maybe thats the cause of your problem.

Try adding some MX records, especially since you are indicating SPF to check MX on “v=spf1 mx a ip4:104.131.28.207 ~all”

This is always a hard subject, and you don’t seem to be listed on any of the major blacklists. But - the mail you’re trying to send screams of advertising, and is probably marked as spam because of it. Adjust your content, and if this is some sort of mailing list, make sure you add a way to unsubscribe.

Or, take the easy way out and use a service like MailGun, Amazon SES or SendGrid. The cost is negligible, but you save yourself a lot of trouble.
