Is AlienMail.io really free?+
Yes β€” during our open beta, all features including warmup, AI writing, unlimited campaigns, and analytics are completely free. No credit card required. When we launch paid plans, early beta users will receive a significant discount.
How is this different from Instantly or Smartlead?+
AlienMail.io combines everything in a unified platform with a superior AI writer, a larger warmup network (120K+ accounts), and real-time deliverability monitoring. Plus we're built mobile-first and offer a true multi-workspace setup for agencies.
What email providers can I connect?+
You can connect any Gmail (GSuite/Workspace), Microsoft Outlook/Office 365, or custom SMTP/IMAP account. We support any provider β€” Zoho, Namecheap, GoDaddy, Fastmail, and more.
Is cold email legal?+
Cold email is legal when done correctly. AlienMail.io is compliant with CAN-SPAM and GDPR by design β€” we include unsubscribe links, handle opt-outs automatically, and provide tools to ensure you're targeting the right contacts.
How long does email warmup take?+
For a brand new domain, we recommend 3–4 weeks of warmup before sending cold outreach. For aged domains with good history, 1–2 weeks is usually enough. Our health score gives you a green light when you're ready.
Can I import leads from other tools?+
Absolutely. Upload via CSV, connect Clay, Apollo, LinkedIn Sales Navigator, or ZoomInfo. Our import wizard maps custom fields automatically so your personalization variables just work.
