When an API response comes back with a field the SDK doesn't recognize, the reques…

Customers can now use the Consent Management API to programmatically re-opt-in users on US and Canada Toll-Free numbers. Previously, opt-outs on US/CA Toll free numbers were strictly enforced at the network level, meaning an opt out block could only be lifted if the user texted an opt-in keyword like "START". Now, if a user provides valid re-opt-in consent outside of a messaging channel (e.g., via…

Effective August 3, 2026, Twilio SendGrid has removed the Send to Coworker action from the Domain Authentication setup flow due to low usage. This simplification prioritizes only the most valuable paths for users to complete their domain authentication and get started with email.
