Mail being sent either from the website itself or through a contact form can often can be marked as spam resulting in the mail either going straight to the spam folder or being caught by a spam filter before reaching the inbox.
You can help ensure the success of your mail delivery by setting up a couple authentication protocols for your domain.
Send using SMTP (Simple Mail Transfer Protocol)
Wondering which one is the best for you? Easy WP SMTP should be adequate for any personal blog or low traffic website, SendGrid is great for businesses who plan to manage email campaigns etc through their website.
Once you have installed the plugin, configure the plugin to send mail using SSL connection. If you are hosted by Serversaurus, you are able to find out what your mail configuration settings are by reading our guide on setting up your mail client, the manual configuration settings mentioned in the article will be the same settings to configure your SMTP plugin.
Note: You are able to configure SMTP to send using your Google, Yahoo, Outlook or any other external mail service however take into consideration that configuring SMTP to send from the server where your website is hosted will give you higher delivery success.
SPF Authentication (Sender Policy Framework)
An SPF record is a entry you can add to your DNS records which shows that the server you are sending mail from is permitted to send mail on behalf of your domain.
Setting up a SPF record will differ dependent on your setup, if you are unsure or would like help please write to us at email@example.com so we can help you identify which providers you will need to include in your SPF record.
