Sequence-R

Sequence-R is a web-based sales emailing platform for automated or semi-automated outreach and follow-up with prospects and clients. Users can build multi-email sequences with custom delays and placeholders, then send messages manually or automatically. A sequence stops when a prospect replies. The AI writing tool drafts initial, follow-up, and closing emails using earlier sequence messages as context.

Its warmup feature connects inboxes, exchanges messages between accounts, simulates replies, and tracks activity on a dashboard. Paid plans add inbox rotation, which the maker says adjusts campaign activity based on inbox health and bounce signals. Contacts can be entered manually or imported from a CSV template. Warmup connections include Gmail, Outlook, and custom SMTP; the maker notes its native Gmail OAuth app is not currently Google-approved and documents IMAP/SMTP as an alternative. The free plan allows one inbox, one active campaign, 400 emails per month, and 100 active records. Paid plans start at $16/mo, and a 14-day trial is listed.
