Avoiding SPAM detection

Avoiding SPAM detection

Option 1 - Send from survey@surveycore.dk

2017/11/02 - We switched to sending email via sendgrid.net, this should help with emails not ending in SPAM folder in users email accounts, please send from survey@surveycore.dk to be sure.


Option 2 - Send from own domain.

Setup your own domain to allow surveycore.dk/sendgrid.net to send email on it's behalf, this is done by changing the TXT record on the domain.
You can use http://www.spfwizard.net/ to generate a correct SPF record if you haven't one setup.

SPF Record before: v=spf1 a:holte.mcg-systems.dk ip4: include:support.zendesk.com include:smtp.zendesk.com ~all
SPF Record after: v=spf1 a:holte.mcg-systems.dk ip4: include:support.zendesk.com include:smtp.zendesk.com include:surveycore.dk ~all

Please note that it can take 4-24 hours before the updated SPF record works.


Validating if emails is detected as SPAM

You can send a test email to a hotmail.com account, they validate SPF records and marks emails as spam if invalid.

1) Send a email to a test hotmaill.com account

2) login to hotmail and select the message and right-click and select View message source.

3) The first 4 lines will show if SPF test was a pass, fail or none if not setup.

Authentication-Results: hotmail.com; spf=pass (sender IP is smtp.mailfrom=survey@surveycore.dk; dkim=none header.d=surveycore.dk; x-hmca=pass header.id=survey@surveycore.dk
X-SID-PRA: survey@surveycore.dk
