I've had several emails to clients fail for the past five days. I am told this is an issue between Siteground and those who use Yahoo email servers (this includes Yahoo,.cs,.aol.,.verizon.net and others). Some fail, others don't. Siteground is 'working on it'...FOR FIVE DAYS. Remaining unresolved. When/if this is rectified, they 'might' send an email, or the will probably post a 'message' on the account, facilitating all users having to log in to see if/when this is fixed. This is at least the third time I've regretted having some of my clients switch to Siteground.
