Hi Tom,

Thanks for your response here, I appreciate the clarification.

As I said earlier my usage is just for the positive reputation allowlist and just in postscreen (I think SpamAssassin also makes use of the list but since a lookup was done just prior in postscreen the local resolver would have the entry cached and not cost an extra query to your servers). Based on one query per connection to postscreen I ran a quick check in my server logs:

# grep -E 'postscreen.*CONNECT' maillog* | wc -l
23651

These logs span slightly over a month back, so as you can imagine a limit of 10,000 queries per month is not enough to satisfy my needs. I do not consider my server to be a high volume or commercial server, I use it for personal and my own business email and I also host email for my local baseball club and umpires association, hardly a commercial endeavor. I believe that your limit of 10,000 queries for the free tier is an order of magnitude too small and a more reasonable number would be 100,000.

That said, it is not my business or place to dictate your company policies, I am fine with you choosing to set the limit wherever you feel is appropriate, but unfortunately a limit of 10,000 queries is too little for me to continue to use the service, which is my choice.

If this limit changes I will happily reconsider.

Hey Simon, Peter and Jaroslaw, I saw this thread and wanted to jump in.

Our reputation data access was introduced many years ago as a free tool and usage has grown significantly.  Recently we’ve seen very high and extreme usage so we added registration for this, and now we’re introducing paid tiers for high-volume use.

As we have real operational costs, we want to work with our heavy users to keep things sustainable and continue delivering a solid experience for everyone.

That said, we’re committed to keeping the service accessible. There’s a free tier available for light usage (10,000 Queries in a rolling 30 days).

And we’ve rolled out other options across our product line for smaller consumers. Our delivery tools for mailers with lighter sending starts at $20 month, complaint FBL starts at $18 year, and email list verification has an entry point at $40.  We also offer nonprofit programs for qualifying orgs.

Feel free to respond to any notification you received directly, or to ping me directly with any feedback or additional questions.

Thanks,

Tom Bartel

    I run postscreen after-220 tests and so it pays to get more servers
    whitelisted to avoid delays.  I was just using the dnswl.org
    <http://dnswl.org> list but I
    found some major senders weren't on it, but were on some other
    lists, so
    I included this one and a couple of others.  I think I can do without
    this list though as I can find others which whitelist the servers I
    need
    to get mail from and it's not worth spending money for my little server
    on it.

    While I tend to agree here, Validity plays with the big boys and
    they're
    allowlist is used by Microsoft among others.  That alone is probably
    good enough to make it worthwhile for senders to pay to get on it and
    they likely don't care about driving away small folks like us.
