Mass Autoresponder Emailing - Any problem with Hosting?

I am using an autoresponder software (Interspire Email Marketer), and installed on one of my site. Now, I am getting around 30-40 email subscribers per day, if it goes grows more than 1000+ in some days, will I get any problem with my hosting? As because of sending 1000+ at a time will be an issue with the hosting company, I think so.

I am not sending any spam emails, all are double-optin email subscribers. How can I be safe with my hosting? I do not want to get trouble after getting 1000's subscribers on my list later on.

You would be best to sign up with Aweber or Getresponse for this. You'll keep your host happy and improve your deliverabilty - and peace of mind too

Aweber and Getresponse are good, but, I got Interspire here for free and it works great like aweber. So, it not a problem with email software, only thing is the hosting, any one can recommend best hosting for this issue?

well, the best solution is really to go with a pro autoresponder service, since almost all the hosts out there which are cheap on hosting fee would have a limit on the number of emails you can send per hour and also per day.
If a hosting provider provides for unlimited emails, then the charge would be too high...so the trade off is to either pay the hosting company or the autoresponder company, and paying to the autoresponder company is much smarter and cheaper.
There are lots of free autoresponders out there, and other that can be available for free...but the problem with the hosting company would still be there.
The hosting company would disable your email sending ability without warning and then you'll have to provide your email and the email address to them to prove that you are not spamming.
Nothing to worry about, but still a hassle to go through...and also loss of time.

So, better sign up for a pro autoresponder and save your self some time and hassle.

There are so many hassles with sending out email, in my opinion it really is worth the $20/month for aweber (or another service).

I think a lot of hosts get nervous even if you are working with double opt lists, especially the cheaper hosts.
