About

K2Mailer is the best unlimited email marketing platform for bulk senders, offering high deliverability, speed, automation and self-hosting.It combines campaign creation, audience segmentation, and automation with deterministic pre-send safeguards that catch issues before a send goes out, plus deliverability infrastructure like sending-domain authentication (SPF, DKIM, DMARC), bounce and complaint processing, and suppression list management. Marketing teams, agencies, SaaS companies, and high-volume senders use it to run everything from newsletters to multi-step drip sequences, with reporting that tracks opens, clicks, bounces, and complaints in one place.Alongside email, K2Mailer's product family includes two standalone tools. PushWave handles web push notifications, letting site owners grow a browser subscriber base and send targeted broadcasts with scheduling, segmentation, and analytics, all without needing a user's email address. The AI Chat Assistant is a configurable website chatbot trained on a business's own documents and URLs, so it can answer visitor questions accurately, capture leads, and hand off to a human when needed.Across all three products, AI is treated as an assistant that speeds up drafting and configuration, never a replacement for human review or K2Mailer's deterministic compliance checks.
