No it's not really complex, you just need to get your PTR and Reverse DNS (rDNS) records for your IP's to be set right, your provider can do this.
But your IP will have to build it's reputation and if someone ever used your IP to spam it would be a huge pain to whitelist it.
Why not just use the free Sendgrid or something similar?
- Hostname + PTR
- SPF
- Landpage on hostname with abuse information (Ex: relay.ginernet.com)
- Check fail-delivery returns and remove from mail-list, prevent double-fail

First you need to warm up your ip address by doing mails in low quantity in initial stage.Once your ip reputation builds than try to increase number of emails gradually.
And try to send emails only subscribed users. than there will be no issue with your SMTP.
Keep proper reverse record of all ip's.
Use SPF and DKIM settings for sender domain.
If you want to know who is marking your email as "report spam" than use FBL .
And monitor your SMTP service and your IP for inclusion in RBLs so you know if things go wrong.
And that is...?
(Edit: I know it stands for feedback loop, but more info would be nice if your experienced with this.)
Most providers now will not white list you just because you ask (or pay). You just need to maintain a good IP reputation and follow all SMTP standards.
Thanks for the list. And DomainKeys, too?
DKIM, yes
Check http://mxtoolbox.com/blacklists.aspx for your mail server's IP on a regular basis in case you get on any blacklists. Typically the response code from the blacklist will include a link to a page where you can find information about getting de-listed. I have found that it's usually a straightforward process: fix the issue with your server and click a button on the blacklist's website, then wait for them to de-list you. For some blacklists it's more complicated than that. I haven't run across any reputable ones so far that require you to pay.
I would also recommend to study existing bulk sending services/platforms such as PostnarkApp or Amazon SES, to understand the full scope of problems you'll have to handle.
When I was building a bulk email services, the primary problem was prompt and proper handling of spam complaints/undeliverables, since even small amount of failures to sort out such events could result in service' IPs blacklisting.
