Emails are not automatically delivered to the recipient’s inbox instead of the spam folder. Nothing is more frustrating than, for example, buying a product from an online store and then digging up confirmation from spam. Or, as a personal example, send a call for tenders for a construction project using the online form…and check the spam folder (in the middle of actual spam emails) for an reply to my email. Even a spam folder is a milder option than having the recipient’s server completely block your mail.
The most common email service providers are: Gmail, Outlook (Microsoft) and Yahoo. These services need to constantly monitor incoming emails and assess whether they belong to your inbox, spam, ads, or some other pre-sorted folder.
In order to receive your own and outgoing automated messages, such as order confirmations, etc., in the recipient’s inbox, the reputation of the sending domain must be in good condition and all necessary security certificates installed. These things should be taken care of from the beginning before you notice problems with email delivery.
Emails sent by homepages are reliably received in the recipient’s inbox when your homepage and domain send messages via SMTP instead of the default WordPress sending method (PHP). For home page messages, it pays to use a reliable SMTP sending service, such as SendGrid, whose main business is delivering emails. Our maintenance and development agreements include SMTP transmission via SendGrid’s API connection at no additional charge. So our customers have no problems with the delivery of emails from the website.
We recommend Google Workspace (formerly G Suite) or Microsoft 365 as your business email provider. It is possible and recommended for them to install three different certificates that increase the reliability of messages coming from your own domain and ensure that your own messages also reach their destination. Large companies that receive a lot of scam messages and other spam have very sensitive radar servers to check the messages. Without proper background work to install Google Workspace or Office 365, your messages may not reach you at all in these cases. Both Google and Microsoft provide relatively easy tools for installing SPF, DKIM, and DMARC certificates and keys, and we do these installations on a regular basis.
Of course, the content of the email itself is also very important. There are many factors in losing reliability that you can read more about here, for example: link. However, the biggest factor affecting reliability is that the recipient himself marks your message as spam, for example in Outlook or Gmail. It is therefore advisable to always think carefully about the content of e-mails in general distribution as well and to ensure that it is only delivered to relevant people.
