Realize there a lot of bulk email services, but what I'm trying to do doesn't feel like bulk email; though maybe I'm just thinking about it the wrong way. Case in point, I attempted to create an account on MailChimp and it wants a subscriber list.
I'm send one, and only one email per address; for example, replying to job postings on Craigslist. I'm not sending follow-up emails, and basically the first email I send is the last to an address unless I get a reply.
Sometimes the email I send is based on a template, other times they've asked for something, and I customize the email. I've automated creating resumes and sending emails in the past, but currently the fastest way just seems to manually do it; meaning I can't imagine sending more than 500 emails in a single day.
As far as I'm able to tell if Gmail, Yahoo, Hotmail, Lycos, AOL, etc. - do not offer the service of paying per email over the send limit, since I'd be willing to pay for the service and be done with this, as it's taking up a huge amount of time and overhead to deal with.
Currently, although I've seen sites giving higher numbers, most of the providers appear to limit emails sent to 20-40 a day; possible I'm doing something wrong, but if I am, I don't understand why these limits are not easy to see within an account, so I'm either able to stay within the limits, or see the service is not a good fit for my needs; currently I just get random error-messages, locked-out, etc.
(If needed, and the setup doesn't take more an a few hours, I'm more than willing to deal with configuring scripts, CSV files, templates, etc. on my computer - as long as they're well documented and the end result addresses the issue; meaning that if I have to send a one-off email, I just copy the template, make the changes, and point to the email. The system must also support attachments, since every email has at least one attachment; best solution would be if I'm able to load an attachment once to the system, then alias it in the local script.)
