90018: 'Template' field is too long

Twilio returns this error when your Broadcast request includes a Template value that exceeds the allowed length for that field. Broadcasts are one-time SMS or email campaigns in Twilio Engage, and Engage campaigns can use Twilio services to power SMS delivery.

• Your request includes an inline Template value that is longer than Twilio accepts.
• You added too much static copy, personalization text, or other message content to the Template field, which caused the request to exceed the field limit.
• You meant to send a saved template by reference, but sent a long inline Template body instead. Use TemplateSid with TemplateLanguage to reference a saved template.

• Shorten the text in Template and resend the request.
• Remove unnecessary copy from the inline template so only the content required for the campaign remains in Template.
• If you want to reuse message content across campaigns, use a saved template reference instead of sending a long inline Template value. Provide TemplateSid and TemplateLanguage when you use a saved template, and do not send Template in the same request.
• Review the content you send through Engage before you launch the Broadcast. If you manage reusable messaging templates, keep them concise and update the template content before resending.
