What is Hunter.io?
Hunter's prospecting stack now runs inside ChatGPT, Claude and Gemini, not only its own app.
Hunter spent the first half of 2026 owning the send: domains, inboxes, warm-up, sequences and recipient-based reporting. The latest batch puts that stack where the user already works. A ChatGPT app with 30+ tools is included on every plan, including Free; Claude, Gemini and Perplexity get native setups; and other clients connect through a hosted MCP server. Discover also flags new matches on saved searches and pre-selects them.
What is Single Grain?
Single Grain keeps publishing marketing-ops how-tos, not product changes.
The Single Grain feed is agency blog content, not a changelog. The November 11 batch covers creative request forms, recruiting email deliverability, CRM retargeting, LinkedIn Ads CRM checks, HubSpot-Salesforce sync fixes, Slack AI agent rules, sponsorship pricing, offline conversion tracking and a Codex versus Claude Code comparison.

Hunter's prospecting stack now runs inside ChatGPT, Claude and Gemini, not only its own app.
◆ Current state
Hunter spent the first half of 2026 owning the send: domains, inboxes, warm-up, sequences and recipient-based reporting. The latest batch puts that stack where the user already works. A ChatGPT app with 30+ tools is included on every plan, including Free; Claude, Gemini and Perplexity get native setups; and other clients connect through a hosted MCP server. Discover also flags new matches on saved searches and pre-selects them.
◆ Where it's heading
The loop of find, send, protect and measure is still the product, but the front door is moving. A user can go from a plain-language request to a prepared sequence without opening Hunter, which leaves data and deliverability as the parts Hunter owns while the interface passes to the assistant. Saved-search alerts fit that shift, since Discover now brings work to the user instead of waiting for a query.
◆ Prediction
Expect the Prompts library and the MCP tool set to grow, along with more Discover signals delivered as ready-to-work lists. The entries do not show whether assistant usage will change credit pricing; existing limits and credits apply for now.
Single Grain
5.0MARKETING
Single Grain keeps publishing marketing-ops how-tos, not product changes.
◆ Current state
The Single Grain feed is agency blog content, not a changelog. The November 11 batch covers creative request forms, recruiting email deliverability, CRM retargeting, LinkedIn Ads CRM checks, HubSpot-Salesforce sync fixes, Slack AI agent rules, sponsorship pricing, offline conversion tracking and a Codex versus Claude Code comparison.
◆ Where it's heading
Posting volume is high and the topics lean on CRM data plumbing and AI tooling for marketing teams. There is no product surface to track; the feed signals what the agency sells, not what it ships.
◆ Prediction
The entries do not support a product prediction; expect more how-to posts on CRM syncing and AI agents in marketing operations.
