Which plan to pickStart free: it's good enough for a founder or a team of three to run their contacts and deals. Plus suits a small team that just needs more room. Go Pro once you want call recording, sequences or proper reporting, and use the 14-day Pro trial to check it's worth it.If you only send email, the Email plan is fine, but compare it with Instantly first. Pick Multichannel if LinkedIn or calls are part of how you sell, since that's what lemlist does best. Add the data add-on ($16 a month billed yearly for 2,000 credits) if you need to find emails and phone numbers. The 14-day trial includes Multichannel features and 200 credits.Start on pay as you go with the free credits, build one agent for your most common call and test it on your own phone. Talk to sales only once you run thousands of minutes a month.
