Best webmailer (Yahoo/Gmail etc. No SMTP)?

Hi,

I want to send many individual emails via Yahoo/Gmail etc (on the webmail, No SMTP).
What are the best up-to-date tools available for that?
I found old posts mentioning blackbulkmail.com and mailerprince.com, anyone still using them successfully?

Thanks

Just make a WTB post and you'll find what you need.
