The verdict
These two get lumped together, but they are built for two different jobs, and that is the whole answer.
Lemlist is the multichannel tool. Email, LinkedIn, calls, WhatsApp and SMS run in one flow, the lead database is built in, and the AI agents do real work across all of it. Instantly is the cold-email engine. Unlimited mailboxes, unlimited warm-up and deliverability tooling built for volume, all wrapped in a UX that gets you sending in minutes.
So the choice comes down to one question: do you need to reach a prospect on more than one channel, or do you need to send a lot of email and have it land? If outreach spans LinkedIn and the phone as well as the inbox, Lemlist wins multichannel outright and is where you should start. If cold email at scale is the whole motion, Instantly wins ease and pricing and is the tool built for it. They tie on warm-up and on deliverability for any normal volume, so neither has the edge there.
A note on honesty: we may earn a commission if you sign up to Lemlist through our links, and we earn nothing from Instantly. It does not move this ranking. Lemlist wins the multichannel breadth it genuinely owns, Instantly wins the ease and pricing it genuinely leads, exactly as the facts read.

Who each is for
Choose Instantly if…
Pick Instantly if cold email is the channel and volume is the game. Unlimited mailboxes under one price, unlimited warm-up on every plan, and deliverability tooling built specifically to keep high-volume sending in the inbox make it the strongest pick for agencies and outbound teams running cold email at scale. The clean single-purpose UX and the AI Copilot get you sending faster, and the price reads honestly because it scales by volume rather than by seat. Just know it is email only, a LinkedIn or SMS step means a second tool.
Choose Lemlist if…
Pick Lemlist if your outreach lives on more than one channel. When a sequence needs to email a prospect, connect on LinkedIn, then follow up with a call or a WhatsApp message, Lemlist runs all of it in one flow, and the 650M-lead database and finder mean you can source the list in the same seat. The Email plan at 39 USD a month with unlimited senders is a genuinely cheap way in, and lemwarm protects deliverability from day one. Go in knowing the multichannel kit sits behind the 109 USD tier and that credits for verification and phone numbers add up on top.
