Anyone using Zoho Mailboxes for outbound I am using with Smartlead. Confused if low reply rate is because of Zoho Mailboxes or Smartlead?? I was using Google mailboxes for 2025- early 2026, that was also low response rates phase...

Hey Asawa, Honestly Zoho mailboxes have always been a bit risky for cold outbound - they don't warm up as well as Google or Microsoft and inbox placement tends to be weaker. That's likely where the issue is coming from. But before switching, check your Smartlead sending settings too - daily send limits, warmup status, and whether your sequences are too aggressive. Sometimes it's a combination of both. If you were on Google and still had low reply rates, the issue might also be in your copy or targeting rather than just the mailbox provider. Worth auditing both before making a change!
