Regie.ai

RegieGO is an agentic sales workspace with built-in enrichment, emailing, dialing and workflows that gets you prospecting end to end from a single chat. Prompt Regie once and it handles your sourcing, ranking, call prep, and follow-ups, so you spend the day talking to active prospects instead of chasing them. Regie learns your voice and your company's pitch, finds the why-now on every account, and writes every message with a compelling reason to respond. Touchpoints across phone, email and social are woven into cohesive plays that build familiarity, so returns compound with every activity. The original genAI sales platform, Regie has delivered and analyzed billions of sales messages. The result is a product pre-baked with the prompts and automations you need to start driving high-quality engagement on day one, rather than weeks of connectors and prompt building.

plusvibe.ai

Cold Email Infrastructure That Lands in Inbox PlusVibe is the outbound sending engine built for teams that measure deliverability, not just volume. Every workspace gets isolated sending queues, dedicated IP pools, and per-mailbox health scoring — so one bad domain never takes down the rest of your campaigns. Most cold email tools bolt on "deliverability features" as an afterthought. PlusVibe treats sending infrastructure as the product. Your warmup runs on adaptive throttling that mirrors real human behavior. Your sending routes through ESP-aware logic that picks the right path for Gmail, Outlook, and Google Workspace inboxes. Your reputation stays clean because the system catches problems before they hit your metrics. Built for Agencies and Scale Operations If you manage outbound for multiple clients, PlusVibe gives you fully isolated workspaces — separate domains, separate IPs, separate warmup pools. One client's aggressive sending never bleeds into another's deliverability. Invite your team, assign permissions, and run 50 client accounts from one dashboard without the spreadsheet chaos. What Makes PlusVibe Different - Isolated sending infrastructure per workspace — dedicated IPs and sending queues that prevent cross-contamination between clients - Adaptive warmup engine — volume curves that respond to real-time bounce and engagement signals, not fixed schedules - Per-mailbox health scoring — every connected inbox gets a live deliverability grade so you catch issues before campaigns stall - ESP-aware routing — sends are optimized based on whether they're hitting Gmail, Outlook, or Google Workspace - Unlimited mailboxes and warmup slots — connect as many inboxes as you need with no per-seat upcharges - Built-in email verification — clean your lists before sending so your bounce rate stays low - Real reply detection — inbox rotation with smart reply tracking that actually works across threads - Agency workspaces — client-level isolation with team permissions, white-label ready PlusVibe is used by B2B agencies, SDR teams, and outbound-led founders who got tired of watching their deliverability decay on platforms that treat infrastructure as someone else's problem.
