When identifying potential partners, consider the following factors:
1. Audience Alignment: Ensure their audience aligns with your target demographic. 2. Reputation: Collaborate with partners who have a strong, positive reputation. 3. Content Quality: The partner should produce high-quality content relevant to your audience. 4. Engagement Metrics: Evaluate their email open rates, click-through rates, and other engagement metrics. 5. Complementary Services: Their services should complement, rather than compete with, yours.
