Honestly, getting on an isp whitelist is a pain and not really worth it for most people. ISPs like Gmail or Yahoo don’t just let anyone on their whitelist—it’s usually reserved for big companies with proven reputations.
Instead, focus on building a good sender score. Use tools like Sender Score by Return Path to monitor your reputation. Also, clean your email list regularly to avoid bounces.
If you’re still struggling, try warming up your IP with tools like Mailshake or Warmup Inbox. It’s a lot easier than chasing an isp whitelist.
