It works really well Anirudh M.. I have been using Instantly.
It's not usually about which platform you are using, instantly or smartlead both usually works.
Google has added a lot of restriction nowadays to identify cold emails, so most probably you might be ending in spam, you need to check how good your deliverability is.
Try to warm up your email accounts, send only 25 emails a day from one account (that's the sweet spot), use a lot of spintax.
If you are scaling, try to get more email accounts instead of increasing the number of emails per account.
Avoid adding the company name or person's name in the subject line, I have seen in my campaigns that they are landing directly in spam.
You need to create a no-brainer offer and provide value upfront. Don't use lead magnets, they don't work anymore. Create a loom video or something that explains how whatever you are providing is gonna generate more revenue for them. That's the game.
Don't send any links or attachments in your first sequence, ask for their permission first and if they say yes then only share it with them.
Try to get a reply even if it is a "no". This will help in boosting your deliverability.
Most importantly, use lead scoring workflow or something to ensure whatever leads you are scraping are right fit for your offer, otherwise no matter whatever you do, they are not gonna reply.
