Cold email - sending limits

[Kirand19833]

Hi,

I'm using Microsoft 365 to send cold emails from a 3rd party tool. I need to send 3000-5000 emails per day. However, Microsoft keeps blocking my account for sending emails. What is an alternative way? I do not want to create multiple email accounts and domains to send these emails out. Is there a tool out there that uses different servers in the backend? Please help me urgently as I need to get the solution asap. Thank you, everyone.

Well, then it's not going to work. You'll need multiple domains and multiple email accounts for that volume.

I've used SendGrid and Gmass to send thousands of emails without getting blocked, but you may want to warm up your domain before going full blast. I've also heard good things about Postmark but never tried it myself.

Check out Maildoso - it was recommended by someone who runs cold email campaigns on behalf of clients and it seems like it has solid deliverability
