To help keep deliverability as high as possible, Mandrill (our email delivery partner) requires that every sending domain is configured to allow Mandrill to send authenticated emails on behalf of that domain.
You'll need to add SPF and DKIM records and verify ownership of your sending domains before you can send email through your Pabau account. This is an advanced feature to be past over to your web domain owner.
Mandrill will not send any email from unverified domains or domains without valid SPF and DKIM records, including public domains like gmail.com, yahoo.com, and more.
Once you have added the DKIM and SPF record, please reach out to support and we can finalise the enabling of your domains to send via Pabau.
