Good one, thanks for sharing

Issue solved? If not yet, happy to help. Quick question - are these Google Workspace accounts? And did you purchase them from a reseller or directly from Google? Could you please record a quick Loom video so I can better understand the issue?

@Zakaria B Looks more like an SMTP connection issue, not Instantly itself. That econnrefused port 465 usually means Instantly can’t connect to the SMTP server at that moment. I’ve seen this happen with some SMTP providers when: • sending limits are hit • too many connections at once • provider temporarily blocks the port Since you’re using ScaledMail SMTP, it might be worth checking with them or reducing the send per inbox a bit to see if it stabilizes. The Outlook accounts working fine also kind of confirms it’s probably provider side, not Instantly. Just my guess though.

In my experience, one possible thing is script reputation / engagement issue, not necessarily warmup or deliverability. When you switched to local biz for 2 weeks, if that niche didn’t engage with the emails much, ESPs might have started seeing that messaging pattern as low engagement and marked them as spam script. Maybe try: - different spintax - new copy angle - slightly different opener - new subject line Sometimes just refreshing the script fixes it pretty quickly.

Hi Nirav, did you find the answer? 350 mailboxes is a lot of sending capacity. Now if you build the prospect list based on your client’s target market, that would be better. And since your client does Media buying, SMM projects and works with eCommerce companies, you can start with a personalization angle, such as: - What platform they use (Shopify, Magento, etc.) - Their monthly traffic - Their current ad spend/pixel installed (if they are already running ads) You can use a tool like Clay to do this automatically. Once you have that info, your first sentence can mention something specific about their store. People reply much faster when they see you actually looked at their business.
