I can’t locate the authentic Yahoo! Mail app for android…I don’t want to have to use the browser on my cell to check my small business email. Help?

It should be there… if its not then you can use the other mail application that comes with the phone.

should I create it in an Excel file or go to my email account and make a large distribution list? Is there and advantage to doing one or the other? Would an Excel file be a better choice if I decide in the future to have an email marketing company use my list to send out an advertisement?

I would strongly recommend using a software called SendBlaster. You can load all your list in that software and mass-message them easily in the future. The software provides detailed stats and reports and lets you choose any email provider’s SMTP servers (even GMAIL) to send your messages.

I am looking to earn an additional income alongside my day job, with tasks to be completed in the evening.
I have thought about offering my services of designing and sending emails for small companies in the local area to help promote and advertise their products and services. This would include looking at the analysis and advising the customer.
Primarily I would take orders through a website, but may promote the idea with cold calling around local businesses
I am a qualified marketing person which adds credence and I have a few years experience of managing these type of campaigns, so I feel it is a natural extension of what I am already doing
Just wanted to know if anyone has any experience of doing anything similar or any thoughts on this idea?

I’m in marketing as well, I’m a sales person. My thoughts would be try to line up some potential clients first and see how that goes. Even if you get one client first and make next o nothing from him it might be worth it to see how you could evolve from that.

I don’t know if you do sales at all in your job but I can grantee you that it will be harder then you think to get clients to come on board unless you have a good connection with them already.

Hope this helps.
