Key features

Boomerang

Send Later
Write an email now and schedule it to send automatically, choosing the time from a calendar picker or by typing a phrase such as "next Monday".
Boomerang reminders
Archives a message and returns it to the inbox at the time you choose, marked unread, starred or placed at the top of the message list.
Response tracking
Reminds you to follow up if nobody replies to a sent message within a set time, or regardless. Read receipts and click tracking are also on every plan.
Meeting scheduling
Suggest Times, Bookable Schedule, Share Free/Busy and Meeting Poll let guests choose a slot from inside the email. Unlimited meetings need Pro or Premium.
Inbox Pause
Stops new email from reaching the inbox until you are ready for it, and can run on a schedule to deliver mail in batches or switch off after work hours.
Respondable
An assistant that uses artificial intelligence to help you write clearer, more actionable emails as you type. Its advanced machine learning features need Pro.

Gmelius

Shared inboxes in Gmail
Group addresses are handled from each person's own Gmail, with assignments, collision detection, shared drafts, team read statuses, tags, and notes with @mentions on a thread.
Meli assistant
Drafts email replies for review, sorts and classifies incoming mail, schedules meetings and follows up. Drafts land in the inbox and nothing is sent without approval.
AI agents
An agent is a standing instruction for one job: it reads incoming mail, acts in connected apps such as a CRM, logs each step, and hands off to a person when its confidence is low.
Automation rules
Rules cover auto-replies, tagging, round-robin and load-balanced assignment, and response-time SLAs. Growth allows up to 10,000 rule executions a month and Pro up to 100,000.
Email analytics
Reports on conversations, team performance, productivity, SLA response times and tags, with weekly or monthly digests by email and CSV export.
Shared labels, views and boards
Gmail labels can be shared across a team, and the plan comparison also lists custom views, Kanban board views, shared email templates and email permalinks.
