Acknowledgments are a must
Most of the readers of this magazine are probably aware that Gmail regards lname.fname@gmail.com as the same as lnamefname@gmail.com. It seems likely that some organisations treat them as different email IDs. That was my interpretation when my emails stopped after I complained about receiving someone else’s statements!
I am hoping that I will stop receiving the wrong statements now that I sent the complaint using the synonymous email ID. However, I will know about this only after a month as there hasn't been a single acknowledgement email.
Would you like to deal with such an organisation if you could avoid it? It seems a pity since this is a commonly used action and it is easy to find sample code for sending an email acknowledgement in various languages.
