The whole outbound stack, automated

The whole outbound stack, automated

  • AI campaign strategist — chat your offer and audience, and the agent builds your campaign name, targeting, and full email sequence with you.
  • Autopilot pipeline runs it all with one approval: verify leads, enrich, write your email, then send — no per-step clicking.
  • Built-in lead verification checks every email before sending, so invalid and risky addresses are caught and excluded automatically.

Smarter signals, safer sending

  • Deliverability tooling gives you a live SPF/DKIM/DMARC checker, inbox warmup, health scoring, and auto-pause when bounce rates climb.
  • Reply detection + AI drafts stop your sequence the moment a prospect replies, classify the reply, and draft your response.
  • Lead temperature moves leads from cold to hot as they engage and reply, so you always know who to follow up with first.
Smarter signals, safer sending

From your offer to replies in three steps

  • Tell the agent your offer — answer a few questions in chat about what you sell and who you target, and your campaign plan builds live as you go.
  • Autopilot does the work, verifying your leads, writing a personalized email for each, and getting everything ready to send.
  • Approve & send — review and hit send. Emails go out from your inboxes on a safe schedule, and replies are detected and drafted for you.
From your offer to replies in three steps

Built to land in the inbox

  • Send from your own inboxes — connect Gmail, Yahoo, Zoho, or any SMTP/IMAP account with an app password. You keep your sender reputation, no shared IP pools.
  • Reads like a real email, with plain-text messages and no tracking pixels or loud footers, so your outreach lands in Primary instead of Promotions or spam.
  • Domain setup, guided — a built-in checker verifies your SPF, DKIM, and DMARC records and walks you through fixing anything that's missing.

AI Agent for Cold Outreach

King Asad was frustrated with cold email platforms that handled sending but left email verification, personalization, and deliverability management to users. Existing tools could send messages but couldn’t decide who to email or how to protect domain health, forcing users to clean lists and monitor deliverability manually. To solve this, Asad created Sendlyio—an AI agent that automates the entire cold email campaign. It verifies leads, drafts personalized emails, checks SPF/DKIM/DMARC, and sends plain-text messages from users’ own inboxes to land in the primary inbox. With Sendlyio, busywork is reduced, deliverability improves, and users only pay for the contacts they reach.
