Underused Mail Setting Retirement
To improve the efficiency of its email delivery infrastructure, Twilio SendGrid retired several underused mail settings.
The following table lists each retired setting and the recommended alternative.
| Mail setting | Alternative |
|---|---|
| Plain Content disables converting plain text emails to HTML. | To maintain open and click tracking, send as HTML. Send plain text emails without open and click tracking. |
| Sections customizes sections of an email content per recipient. | Use Twilio SendGrid transactional templates with handlebars syntax through the v3 API. |
| BCC automatically BCCs an email address for every email sent. | Add a bcc as a personalization in each API call. |
| Spam Checker checks outbound messages for spam content. | Maximize deliverability with Email Testing. |
| Drop feature tests email processing. | Use Sandbox Mode. Send a test email without delivering the email to any recipients. |
| DomainKey signs emails. | Use DKIM, the standard for signing emails. |
The following table lists each removed integration and the recommended alternative.
| Third-party integration | Alternative. |
|---|---|
| Gravatar | Sunset due to low customer adoption. |
| Sendwithus | Use Twilio SendGrid Marketing Campaigns. |
