Your prospects are heavily Gmail, you're budget-sensitive, and you accept shared-infrastructure tradeoffs. Typical buyers: early-stage SaaS founders, smaller agencies, solo SDRs.

Puzzle Inbox as Alternative

Puzzle Inbox offers both Google Workspace ($3 to $4.50 per inbox) and Outlook 365 ($0.35 per inbox). Pre-warmed. Dedicated inboxes on isolated infrastructure. WhatsApp support in under 15 minutes.

Compared to Primeforge: significantly lower pricing for similar dual-platform coverage. Pre-warming included by default. Faster support.

Compared to Mailforge: more competitive Outlook pricing. Both platforms in one provider versus Mailforge's Google focus. Better support response times.

Verdict: Primeforge is the right pick within Salesforge's product line if you need both Google and Microsoft and can afford premium pricing. Mailforge fits Google-heavy budget operations.
