  <p>We send around 200k emails per month from ~ 25 domains, all on the same IP. We haven't had issues being blacklisted, but some clients have had issues with their domain appearing on some blacklists, especially if it was their first mailing (with invalid addresses).</p>

Answers.Body: <p>Getting your own IP with SparkPost doesn't lessen their activity or responsibility under their contract to provide whitelisting for you. It probably makes it easier for them to respond quickly and effectively when it does happen.

  <p>One of my clients sends  600k+ emails / month with sendgrid on a private IP. They were very helpful when we got blacklisted due to a new type of attack (bringing down a small set of inboxes, in this case mainly .gov, by having a bot submit subscribe requests simultaneously to a very large number of sites).

  During testing of sparkpost we are getting into the inbox with gmail, yahoo and aol, but not with microsoft. We are getting an 8 on microsoft's [bulk complaint level](https://technet.microsoft.com/en-us/library/dn759623%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396) which AFAIK is associated with the IP used.

  If you are on a dedicated IP, how many emails per month are you sending? Has monitoring your dedicated IP for blacklisting been an issue?
  
  If you are on a shared IP (either on sparkpost or other servers) have you had trouble getting into microsoft inboxes or with the BCL? Thanks in advance for all your thoughts.

  That's one of Sparkpost's responsibilities (although you should also monitor, just in case, I particularly like <http://multirbl.valli.org/lookup/>).
