I recommend using a free service called SpyPig to include an invisible image in the email that will notify you when the email is opened (if images are enabled). I usually wait about 10 minutes after the notification and call the client or lead and ask them if they had a minute to check my email. They usually say something like "Yeah you have perfect timing, I just took a look at it..." It's a pretty slick little trick http://www.spypig.com/ Good luck!

How does that get around a number of email clients flagging the warning that 'this email contains links to external images' or things of that nature? (Gmail does it, Thunderbird does it, I'm sure most modern email clients have that).

To me that would come across as, at best, annoying and at worst, suspicious.

Instead of an invisible tracking image make it part of your signature, like a company logo or something similar.

Tout will do that for you, automatically.

Oh, you're good.

Whoa, I think calling people after only 10 mins after I've sent the mail is pretty obtrusive. Surely I would give them enough time to read the mail, think about it and give me a reply whenever they're able to (within a reasonable amount of time, say 2 hours).

He calls 10 minutes after they have read the email as per SpyPig. That we he does indeed have perfect timing.

I often look at mails, move them to 'ToDo' and then only read them later. ToDo means it has no priority and I may get to it tomorrow. An immediate call would force me to context switch and I don't think I would like it.
