I'm Heleen from crowdbeamer. When website visitors come to our site and subscribe to our newsletter, we sent them an email with Zoho Campaigns to confirm their email address. We have been running some tests and the confirmation email seems to be sent to the spam folder. Although our SPF and DKIM are verified in Zoho Campaigns (see attachment). 

What can we do more to prevent the email to be send to the spam folder. 

Kind regards,

Heleen Persoon
