Ensure website's blog page subscription feature outbound e-mails work correctly

Job ID: 38619557

Budget: $250 – $750 USD

PROBLEM TO SOLVE: My web domain is currently hosted on Squarespace (formerly on Google) and my website is built with Wix. I suspect this has caused problems with having my blogpage subscriptions working correctly and with people getting the automatic outbound e-mails they should. Though I followed instructions in getting CNAMES and MX records authenticated, no outbound e-mails are sent.

I am interested in having someone explain to me the most cost-effective approach to solving this problem, and then we would execute the best one. this seems to me a choice between one of three solutions:
1. Figure out how to get my outbound notifications working with my current arrangement (hosted on Squarespace, built on Wix)
2. Transfer my Web domain to be hosted by Wix instead of Squarespace
3. Transfer the hosting of my Web pages to Squarespace instead of Wix.
