If your pitch gets rejected, should you keep following up?

The best approach is to respect their initial decision but maintain a long-term perspective. Keeping their information allows you to monitor their content for future opportunities that align with your expertise, demonstrating persistence without being pushy. Sharing new ideas immediately after a rejection can be perceived as ignoring their feedback. Assuming they will eventually say yes can lead to unproductive and potentially annoying follow-ups. While a "no" means they're not interested at that moment, it doesn't necessarily mean they'll never be interested in the future, especially if circumstances or their content focus changes.
