Case Study
“Salesforge and your other products, and your fast support team were crucial in my first 2 years running a lead generation agency. As a solo founder, generating leads for myself and my clients is challenging. Salesforge helped me create a "lean and mean" pipeline. With a small investment of time and money, I often receive so many leads that I have to pause my campaigns.”
Vytas Mikulenas
Founder, Lean Sales Systems
“I've used many platforms and no one beats Salesforge on email deliverability and ease of use. Every week the team adds new features and the support is excellent!”
Sam Momani
CEO, LinkedDNA
"Salesforge's new infrastructure is a game-changer. Big boost for my deliverability and sending capacity. I've tried multiple outreach tools and let me tell you: it's a must-have for everyone that is serious about cold emailing at scale."
Roman Hipp
Co-founder, bettercontact.rocks
"Our CAC is currently $2.86, and we expect it to decrease even further. We’re currently onboarding 4 to 5 new music creators every day. We truly believe in what you’re building at Salesforge. Your guidance on how to scale and reach the right customers has been a game changer for us. Tying your strategy of setting up domains + inboxes + warming up + daily limits with our royalty audit lead magnet has allowed us to grow efficiently, bringing in strong results without excessive effort. It’s made a real difference."

Questions fréquemment demandées

Si nous ne répondons pas à votre question ci-dessous, veuillez nous contacter par chat.

How long does it take to warm up a mailbox?

The ideal warmup period is 2 weeks before sending cold outreach. Some mailboxes may need 4 to 6 weeks depending on the provider and sending history. Keep Warm-Up always-on after that to maintain deliverability.

Does Warm-Up work with my existing mailboxes?

Yes. Warm-Up works with any standard mailbox provider, including Gmail, Outlook, Yahoo, Zoho, and custom domains. If you're using Salesforge, you also get free warmup for any mailbox you create inside the platform.

What is a Heat Score?

Heat Score is a real-time measure of mailbox health from 0 to 100. A score of 85 or higher means your mailbox is ready for outreach. Heat Score updates daily based on inbox placement, warmup engagement, and authentication status.

Can AI assistants use Warm-Up directly?

Yes. The Warmforge MCP server connects to Claude, Cursor, and other MCP-compatible AI clients. Your AI assistant can manage mailboxes, pull warmup stats, and run placement tests directly from a chat prompt.
