What is Postigo and what is it for?

Postigo is a cold email outreach platform that solves three problems at once: SMTP account rotation, AI content variation, and automatic reply parsing. If your goal is to send cold emails to potential clients or leads, and deliverability is important to you, not graphics and templates, Postigo is a good fit.

How it differs from classic ESPs

Mailchimp, SendGrid, ActiveCampaign, and similar services are about marketing email: the subscriber has given consent, is waiting for your email, and opens it out of habit. They have a shared IP pool, templates, and a newsletter mode. This format is not suitable for cold outreach: the shared IP quickly ends up on a blacklist, and providers instantly recognize identical templates.

Postigo is built for cold email: you connect your own SMTP accounts (Gmail, Outlook, Amazon SES, corporate), AI makes each email slightly different, and IMAP automatically retrieves replies. The platform does not send from shared IPs - your reputation is always in your hands.

What's included in the platform

• SMTP rotation with per-account limits and automatic shutdown of failed accounts
• AI-powered generation and rotation of subject lines/content every N emails
• IMAP-sync of replies + AI-classification into positive / negative / question / bounce
• Follow-up emails based on AI-classification of responses
• Analytics: funnel, graphs by day, breakdown by SMTP and subject lines
• REST API + Webhooks for integration with CRM/Zapier
• Built-in validators for SPF/DKIM/DMARC, MX, blacklist

Who is it suitable for

B2B sales teams, lead generation agencies, outreach freelancers, and anyone who needs to send a lot of emails to a cold base with deliverability control. Pay-as-you-go without subscriptions - you only pay for what you send.
