Not receiving certain e-mails

[#1]

Any of  you Plusnetters who also run for exercise and 'fun' have probably heard of Parkrun, and those of you who also do Parkrun will receive a "your personal result" e-mail after each event you do, so you will know what I am talking about.
I was getting my result e-mail until about 2 weeks ago when they suddenly stopped. My local Parkrun tell me they are still sending these e-mails, but I think the person I was talking to may have mistaken text messages for e-mails. They told me to go onto my profile on the Parkrun web-site and reset the e-mail option, but there doesn't seem to be an option for this - there is for the newsletter e-mail, the volunteer e-mails, and I can set up the text message, but not the personal result e-mail. The Parkrun web-site suggests that if you are not receiving this e-mail, it might be ending up in the Spam bin at the ISP, but I cannot find any sign in my Plusnet account of anything set up to redirect this particular e-mail to anything other than to me.
Please, if anyone has any suggestions, would you lety me know what you think.
Thanks

Guess what? My personal result e-mail arrived today. Hopefully that means problem solved.

Remember if something is flagged as Spam by Plusnet it will go into your Spam email box at webmail even if you've not set it to be so directed. I have to keep checking the Spam box daily because legitimate ones often get trapped. In theory you can whitelist but whitelisting everything would be overly onerous.

You only need to white list the ones you trust.  If they are not from shared domains (e.g. @gmail.com) you could whitelist the whole domain.
