We did the wrong by supporting Mandrill. Mandrill, SendGrid – all are Cloud Transactional Email Services. We had easy guide to integrate Mandrill with WordPress to receive email from contact us form, integrating Mandrill with XenForo. SendGrid is Known Cloud Transactional Email Service With Free Quota. Here is an Easy WordPress Mandrill Alternative SendGrid Transition Guide. Mandrill suddenly fully closed their free Quota of usage.

But a Transactional Email Service is better to have. This guide is for new WordPress users. SendGrid has many advanced functions, we will write the easy steps for only somehow making the contact us form working. SendGrid may be complicated to a new user.

_domainkey.thecustomizewindows.com" 5 min TXT v=DKIM1\; k=rsa\; p=MIGfMA0GCSqGSI vWob2OaKynO8/lQIDAQAB\;"
