What to post
- Ask for critique on a sales motion with segment, ACV, and sales cycle context.

- Rule to remember
- Our community requires users to have 10 upvotes received on comments here before you will be allowed to create a new post or lead a discussion. Karma farming is asking for upvotes in the comments section of other users posts and should be reported to the mod team for removal.
3
r/Emailmarketing
Marketing and growth communities
Why join
r/Emailmarketing is useful for permission-based lifecycle and newsletter growth, but not cold email.
What to post
- Ask about segmentation, deliverability, or nurture strategy with real constraints.

- Rule to remember

4

What to post
- Ask for help diagnosing a paid lead-quality problem with campaign context.
- Share what changed after adjusting audience, bidding, or conversion tracking.
What to avoid
Avoid agency promotion, surveys, and tool posts that do not solve a PPC problem.
