Line One

Line One brings supported email and SMS conversations into a single inbox so users can review communication without constantly switching between separate services.

Connect eligible Gmail, Microsoft email, and Twilio SMS channels. Line One preserves the source of each message while organizing conversations into a consistent workspace. Reply through the appropriate connected channel or compose a new email or text from an eligible account.

Features include:

• Unified inbox for supported email and SMS channels

• Gmail and Microsoft email connections

• Twilio SMS connections

• Conversation search, filters, and stars

• Replies through the appropriate source channel

• New email and SMS composition

• Connected calendar views

• Tasks and follow-up context

• Notification controls

• Channel and account management

• Privacy, diagnostic, subscription, and account-deletion controls

Line One organizes supported connected services; it does not replace the underlying email, SMS, or calendar provider. Message delivery, availability, retention, and provider-side processing remain subject to each connected provider’s systems and policies.

The app is free to download and supported by advertising. Optional in-app purchases can remove ads or unlock additional features. Pricing is displayed in Google Play and may vary by region.
