MailBeast is an all-in-one cold email platform designed for B2B sales teams, lead generation agencies, and startups. It combines email sequences, SMTP management, warmup, and AI-powered sending & inbox management into a single platform.
MailBeast offers unlimited SMTP account connections on all plans. Whether you're managing 5 accounts or 500, there are no per-account fees or hidden limits.
Each plan comes with generous monthly sending limits - significantly higher than most competitors at a fraction of the cost. These limits apply to campaign emails only. Warmup emails don't count against your quota. If you need higher volume, you can easily add more with plan add-ons.
We recommend sending no more than 30 emails per account per day after warmup to maintain good deliverability. Platform limits are set as safety guardrails to protect your accounts from ESP bans - but you can adjust these thresholds based on your own experience and risk tolerance.
Yes, warmup is included at no extra cost on all plans. Every connected email account gets automatic warmup to build and maintain sender reputation - no third-party tools needed.
AI Sending Mode analyzes your lead dataset and automatically enriches it with company information from the web. Based on data completeness (shown as Dataset Quality Score), the system selects one of three personalization modes - from light touches using name and company, to deep personalization with specific facts about their business. You configure the tone, language, and conversation goal through a simple wizard, and fallback templates ensure every email gets sent even if AI fails to personalize based on provided dataset.
Yes. Our multi-factor bot detection removes email security scanners and automated clicks from your analytics. You see real engagement metrics - not inflated numbers from Outlook, Gmail, or corporate security tools.
Absolutely. MailBeast includes unlimited team seats on all plans. Add SDRs, account executives, managers, or clients without per-seat charges.
All plans include chat support with fast response times. Higher-tier plans include priority support to help you get the most out of the platform.
