GMass raised prices after a decade, while shipping deliverability and SMS-adjacent features
GMass, the Gmail-based mass-email tool, is shipping a steady stream of practical capability around its core: per-recipient time-zone sending, text alerts for campaign replies, an AI template builder, and open-tracking hardening for cleaner open rates. The headline event in the window is its first pricing change in ten years, framed around a decade of growth and 9 billion emails sent. A referral program rounds out the go-to-market motion.
Clay adds open-weight models to cut the cost of AI-driven GTM research
Clay is a data-enrichment and go-to-market workbench whose center of gravity has shifted to Claygent, its AI research agent, and to Audiences, its list-building surface. Its weekly Product Roundups read like a platform maturing on every axis at once: new data sources, deeper credit-spend observability, CRM mappings, and enterprise controls like static IPs and sensitive-connection governance. The recurring thread is making AI research cheaper to run, easier to trust, and safer to deploy inside large teams.

The headline event in the window is its first pricing change in ten years, framed around a decade of growth and 9 billion emails sent. A referral program rounds out the go-to-market motion.
GMass is maturing from a power-user Gmail add-on toward a more complete sending platform: features increasingly target deliverability accuracy and cross-channel reach (email-to-SMS, reply alerts), and the pricing reset signals confidence and a need to fund that expansion. The comparison content against tools like Mailmeteor shows it defending the no-limits, Gmail-native niche while moving upmarket.
Expect GMass to keep investing in deliverability and tracking accuracy and to lean further into SMS/cross-channel touches, with the new pricing underwriting the roadmap. Watch for whether the January 2026 price change reshapes its positioning against cheaper mail-merge competitors.

Two arcs dominate. First, cost and observability: sandbox modes that let you validate AI columns before burning credits, per-function spend attribution, and now cheaper open-weight models all attack the same problem, that agentic research gets expensive at scale. Second, distribution: Clay is pushing its Functions into the agent surfaces its users already work in, from Codex to inbound-email automation, so the research layer runs wherever the rep is. The product is positioning itself as the GTM data engine other agents call, not just a table you sit in.
Expect continued work on cost controls and model choice inside Claygent, plus more embedding of Clay Functions into external agent runtimes. The credit economics of AI research are clearly a strategic front.
