I am developing a mobile app startup. I have gathered a database of 2,000 people (closely related to an industry) and I want to send out cold emails to them advertising my app (through MailChimp, MailerLite or something similar). Since these are cold emails, I realized I may need at least two domains (not using my main one) and at least four inboxes for each domain (based on what I read online). I plan to send out these 2,000 emails over about 10 days. This would be around 26 emails per inbox per day, which shouldn’t be too bad, I think.
Therefore, I am looking for the cheapest option for these mailboxes. I currently have a Microsoft Office Standard subscription for myself, and I found that there is “Exchange Online” (AUD 6) and “Exchange Online Kiosk” (AUD 3) available. I would prefer to use the Online Kiosk since it’s the cheapest option. Please let me know if this is a good idea. I just need a mailbox without anything else for newsletter.
If anyone has had a similar experience or knowledge, please share.
