About Sendlyio
What is Sendlyio?
Sendlyio is an AI-powered cold email automation tool that runs your entire outreach on autopilot. You tell the agent about your offer, and it verifies leads, writes personalized emails, and sends them from your own inboxes (Gmail, Yahoo, Zoho, or any SMTP/IMAP) to land in the primary inbox—not spam.
Problems it solves
Cold email outreach is time-consuming and often lands in spam. Sendlyio automates the whole process: lead verification, email writing, deliverability checks (SPF/DKIM/DMARC), reply detection, and even draft responses. It also warms up your inboxes and auto-pauses if bounce rates climb, so you maintain sender reputation.
Who it's for
Ideal for sales teams, founders, and marketers who want to run cold email campaigns without manual setup. It's not for those who need heavy manual control over every step or prefer using shared IP pools—Sendlyio is built around your own sending infrastructure.
Real use cases
Use it to launch a campaign in a day: connect an inbox, answer a few questions about your offer and audience, and the AI agent builds your campaign strategy, sequence, and sends on a safe schedule. It's great for lead generation, appointment setting, and following up with prospects automatically.
Key features
- AI campaign strategist — Chat your offer and audience; the agent builds campaign name, targeting, and full email sequence.
- Autopilot pipeline — One approval runs lead verification, enrichment, email writing, and sending—no per-step clicking.
- Built-in lead verification — Every email is verified before sending; invalid and risky addresses are automatically excluded.
- Deliverability tooling — Live SPF/DKIM/DMARC checker, inbox warmup, health scoring, and auto-pause when bounce rates climb.
- Reply detection + AI drafts — Sequences stop on a reply; Sendlyio classifies and drafts your response.
- Lead temperature — Leads move from cold to hot as they engage, so you know who to follow up with first.
