Hey! So, the isp whitelist thing is kinda overhyped unless you're sending *massive* volumes of email. For smaller websites, it’s usually not necessary. Instead, focus on improving your email sender reputation.
Tools like Mail Tester or GlockApps can help you check your email deliverability. Also, make sure your domain has SPF, DKIM, and DMARC set up properly. These are way more important than trying to get on an isp whitelist.
If you’re still having issues, consider using an email service provider like SendGrid or Mailgun. They handle a lot of the heavy lifting for you.
