Email Expert Needed: Improve My Email Deliverability -- 3

Email Deliverability Our company wants to get our systems organized and in one place. We need to ensure that our programs can effectively send out and receive emails everywhere in the world without being blacklisted or going into spam. Currently, our emails are set up in GSuite but are hosted on TMDHosting.com. Our domains were purchased from GoDaddy (mostly) and are hosted on [login to view URL] and on ionos.com. We currently send out emails from 3 sources: 1. Google Suite (gmail) 2. [login to view URL] 3. [login to view URL] In the past, we’ve allowed “Email Specialists” to come in and change our settings and they’ve often damaged our email system. One thought they were helping but we immediately could not send out emails. Another tried to help and it too hurt our ability to send out emails. We can not afford for our emails to go down even for one second. So, in order to avoid that, we would like to focus on fixing emails coming from a domain that we do not use often. We would like to fix [login to view URL] Here’s what we would like to do. 1. Move the email hosting for [login to view URL] back over to Google Suite (without causing any downtime in our emails being sent or received). 2. Set up an email TBD to send/receive email effectively in Google / Gmail, Zoho, and MailChimp - Again, without any disruption in sending or receiving emails!!! 3. Set up DKIM and SPF for Google Suite, Zoho, and MailChimp so all three can be used to send out mass emails.
