About

Extra Thursday is an AI-powered inbox assistant that connects to your Gmail and Google Calendar (via OAuth) to transform email management into a fast, context-aware, streamlined workflow. It treats your inbox like a database: it can scan thousands of emails in seconds, extract key insights or open loops, surface important threads, and highlight action items, so you don’t have to manually sort, search, or triage messages. Extra Thursday also drafts professional replies (from polite follow-ups to technical responses), auto-generates follow-up emails, and lets you review/edit before sending, dramatically reducing the time you spend writing and replying. With deep-context AI reading and understanding entire conversations, the platform helps manage email overload and makes your inbox actionable, rather than overwhelming. Privacy-wise, emails and calendar data are only fetched on demand per session; Extra Thursday does not store your full inbox or use your content to train its models.

About

Sendio’s Opt-Inbox is a proprietary sender management process, acting on messages having cleared email security, which would otherwise be released into a user’s inbox, ensuring that recipients only receive messages from desirable sources, whether from individuals or subscriptions, leaving the new yet undecided sources to the recipient’s discretion in a queue separate from the usually messy quarantine queue. Despite being protected by advanced email security systems, many inboxes continue to be inundated with countless security-cleared messages comprised of persistent sales pitches and marketing communications, distribution lists and bulk sources. Separating harmful messages in the quarantine queue from nuisance and potentially desired ones is increasingly difficult. This can become particularly troublesome for executives and professionals who can’t afford to overlook an important email and find out later they had a desirable message (false positive) in their cluttered quarantine queue.
