As we continuously modernize our email delivery infrastructure, we have sunset some sparsely used features in order to improve efficiency.
|Mail Setting||Recommended Action|
|Plain Content is an option within SendGrid Mail Settings that disables the automatic conversion of plain text emails to HTML.||If you would like to maintain open and click tracking, you must send HTML. Otherwise, you can continue sending plain text emails without open and click tracking.|
|Gravatar third party integration.||Due to low adoption among customers we decided to sunset this feature.|
|Sections is a form of mail merge where sections of an email content can be customized by recipient.||We recommend using Twilio SendGrid transactional templates with handlebars syntax through our v3 API.|
|BCC automatically BCCs an email address for every email sent.||We recommend identifying bcc as a personalization in each API call.|
|Spam Checker is an option within SendGrid Mail Settings that checks outbound messages for spam content.||We recommend using Email Testing to maximize your deliverability.|
|Drop feature is a test feature that goes through the processing of mail, but just drops it without delivering in the end.||We have a Sandbox Mode feature which allows you to send a test email to ensure that your request body is formatted correctly without delivering the email to any of your recipients.|
|Sendwithus third party Integration||We recommend using Twilio SendGrid Marketing Campaigns.|
|DomainKey is an old feature for signing emails which has been deprecated by email industry.||Users should utilize DKIM which is the new standard for signing emails.|
