I have managed few ecommerce websites for my clients. For few months I have been using optinmagic.io to collect leads and I am amazed how its working pretty perfectly. OptinMagic has some great ready-made templates.
The best part of optinmagic is they have a free plan. Highly recommended.
The best lead generating platform that will really work for your business are LinkedIn, Reddit, Crunchbase, entracker and startup talky. For managing the leads yo can use Corefactors AI CRM(https://www.corefactors.in/)
