For those wondering what are we doing differently than one of the biggest tools available on market. Worth a quick read. https://www.sendstate.app/compare/sendstate-vs-instantly

Cold email tools optimize opens. We decided to optimize revenue. Today we shipped Revenue Intelligence inside SendState. Now you can track: Sent -> Positive reply -> Meeting -> Closed -> Revenue. You see revenue per 1,000 emails. Revenue per inbox. Revenue per messaging angle. Not just “did they reply” But “did it make money” We also added: - Angle revenue heatmap - Inbox profitability ranking - Revenue-aware Campaign Advisor The system now adapts not only to replies, but to what actually closes. Cold email isn’t about sending more. It’s about scaling what generates revenue. SendState just became an outbound operating system.

Smartlead and SendState both serve outbound teams, but they are built around different philosophies. You can read more about it here: https://www.sendstate.app/compare/sendstate-vs-smartlead

We’ve just expanded the technical documentation behind SendState’s core architecture. Most cold email tools focus on sending volume. What we’ve been building instead is a structured decision layer that governs what happens after the send reply classification, prospect-level autopause, deliverability protection, quality gates, and full decision explainability. If you're interested in the system-level breakdown of how the Outbound Intelligence OS works, including architecture, signal processing layers, and real workflow examples, I’ve written a full technical overview here: https://www.sendstate.app/outbound-intelligence-os This update reflects how we think about outbound not as a sending tool, but as a managed system.

Quick overview what has been implemented on SendState today: A/B Test Results 
Added variant performance comparison on the campaign detail page — shows reply rates per variant, determines a winner (needs 5+ sends and 5%+ difference), and displays visual side-by-side comparison. Domain Authentication Checker 
Built a DNS-based validator for SPF, DKIM, DMARC, and MX records with a 0-100 health score and actionable recommendations. Lives in the deliverability dashboard, no database needed. Prospect Tags 
Full tagging system create color-coded tags, assign/remove them on prospects, inline tag display with a picker component, and search support. Fixed an infinite loop bug in the TagPicker later in the day. Campaign Cloning 
Clone button on campaigns list that copies the campaign shell and sequence steps (not prospects) into a new draft campaign. Campaign Archiving 
Archive/unarchive toggle on campaigns with filtered views so you can hide old campaigns without deleting them. Global Suppression List + Unsubscribe
Full suppression management page with single add, bulk import, search, and delete. Public unsubscribe landing page with token-based flow. Rate-limited unsubscribe API that adds to suppression list automatically. Template Library 
Save email content as reusable templates with categories. Browse/search/filter modal integrated into the campaign sequence editor. "Save as Template" button appears when a step has content. Email Warmup Manager 
Per-mailbox warmup configuration starting at 5 emails/day with customizable target and daily increment. Progress visualization with estimated completion dates. Includes a best practices guide section.
