Case Study
„Salesforge und Ihre anderen Produkte sowie Ihr schneller Support waren in meinen ersten zwei Jahren als Leiter einer Agentur für Lead-Generierung von entscheidender Bedeutung. Als alleiniger Gründer ist es eine Herausforderung, Leads für mich selbst und meine Kunden zu generieren. Salesforge hat mir dabei geholfen, eine „schlanke und effiziente” Pipeline aufzubauen. Mit einem geringen Aufwand an Zeit und Geld erhalte ich oft so viele Leads, dass ich meine Kampagnen unterbrechen muss.”
Vytas Mikulenas
Founder, Lean Sales Systems
„Ich habe schon viele Plattformen ausprobiert, aber keine ist besser als Salesforge, was die Zustellbarkeit von E-Mails und die Benutzerfreundlichkeit angeht. Jede Woche fügt das Team neue Funktionen hinzu und der Support ist ausgezeichnet!“
Sam Momani
CEO, LinkedDNA
„Die neue Infrastruktur von Salesforge ist bahnbrechend. Sie hat meine Zustellbarkeit und Versandkapazität erheblich verbessert. Ich habe mehrere Outreach-Tools ausprobiert und kann Ihnen sagen: Dieses Tool ist ein Muss für alle, die ernsthaft daran interessiert sind, Cold E-Mails in großem Umfang zu versenden.“
Roman Hipp
Co-founder, bettercontact.rocks
„Unser CAC liegt derzeit bei 2,86 $ und wir gehen davon aus, dass er noch weiter sinken wird. Derzeit gewinnen wir täglich 4 bis 5 neue Musikschaffende hinzu. Wir glauben fest an das, was Sie bei Salesforge aufbauen. Ihre Anleitung, wie wir skalieren und die richtigen Kunden erreichen können, hat für uns einen entscheidenden Unterschied gemacht. Die Verknüpfung Ihrer Strategie aus Einrichtung von Domains + Posteingängen + Warm-up + Tageslimits mit unserem Lead-Magneten für Lizenzgebühren-Audits hat uns ein effizientes Wachstum ermöglicht und ohne übermäßigen Aufwand zu starken Ergebnissen geführt. Das hat wirklich einen Unterschied gemacht.“

Frequently asked questions

If we don’t answer your question below, please contact us via 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.
