You never want an email to look like this in an inbox:
In this instance, a client had purchased domain based email from Google. We set up her website with a Contact form, and of course there was an email link, well.
Many email providers (including Google/GSuite, Gmail) will spam filter by checking whether your email originates from the same domain noted in the From Email. For example, if your email claims to be sent from your Gmail address but is actually sent from your website’s server (rather than Gmail’s server), your email may be sent to spam or not be delivered at all.
Our job at AOS was to make sure the FROM address and the SMTP address matched so as not to trigger spam warnings.
The explanation was step-by-step perfect, and it worked perfectly. This is a must for any site to ensure that the From address matches the server the mail is coming from to spam proof your clients’ emails.
Similarly, be certain to authenticate domains for emails being sent from Mailchimp. If not DKIM authenticated, emails from Mailchimp newsletters will receive similar warnings – or just be dumped into spam. Read our blog post on Fix: Emails from Mailchimp Marked as Potential Spam.
