Looking for help with configuring the Domain DNS settings for my store. When sending out invoices or customer account activations they always go to their spam folder. I know this is because my DNS settings aren't correct (TXT and MX records). I have tried the values Google says I require and also what shopify says for those records and the problem persists. They both offer differing values for those records.
Does anyone else use the same services as me and can let me know what values I should have as my TXT and MX records to avoid this problem? I would appreciate it a lot, it's so embarrassing to have to send a follow up email telling people to check their spam folder for my correspondence.
