Instantly.ai vs lemlist
Features, pricing, strengths and trade-offs — and which one fits your situation.
The verdict
Editor’s verdict
Instantly.ai focuses on high-volume cold email, while lemlist focuses on multichannel sequences that mix email with LinkedIn, calls and WhatsApp. Choose Instantly.ai if email is your main channel, you want unlimited sending accounts with warm-up at a flat price, and you plan to scale volume across many domains. Choose lemlist if LinkedIn visits, invites and messages need to sit alongside emails in the same cadence, you want a built-in dialer, or you value image and video personalization. lemlist's multichannel features require its per-user Multichannel plan, so costs grow with team size, while Instantly's pricing is tied to email volume and contacts. Both include a lead database and warm-up, so the channel mix is the main deciding factor. Neither provides a full CRM of record for managing deals at scale; HubSpot is better suited there.
Neither has a permanent free plan, but you can start with a free trial.
