Sending e-mail in large numbers

问题

I am developing an application that needs to inform users (around 1800) on a regular basis (weekly).

I consider gmail but it has a 500 mail in 24 policy, Google groups don't have an API, I contact my web hosting company (bluehost) about the situation, they don't return with an adequate answer (they don't mention the exact number that I can send daily )

Any suggestion would be great...

Thanks

Your web host should allow sending of mass emails, and should have facility to set up reverse DNS etc on your smtp server, since its not uncommon for the web? 1800 mails is a relatively low in my opinion.

Signing up to a email marketing provider as Shoban mentioned is probably the best option.

Well you dont have much options left

1. Change your hosting provider
2. Use a paid email marketing provider like graphicmail
