The number of influencers to approach during the outreach process can vary based on the type of campaign, budget, and your marketing strategy. There are no set rules, but here are some guidelines:

1. Campaign Goals: For wider brand awareness, a large number of micro-influencers might be ideal. For more focused campaigns, working with fewer, highly relevant influencers that align with your brand might be more beneficial.

2. Available Resources: Consider your team’s ability to manage relationships with influencers. If you’re running a campaign with multiple influencers, you’d need adequate resources and time to manage these collaborations.

3. Influencer Engagement: A smaller number of influencers often means more time can be spent on nurturing each relationship.

4. Risk Management: Engaging with more influencers can be beneficial in spreading risk. If an influencer underperforms or there are issues, it’s less impacting when you work with a larger pool.

Using an influencer marketing platform like Flinque can help you find the right influencers, manage those relationships, and analyze campaign results, making the process more manageable. Other platforms also offer similar capabilities. Ultimately, the best approach depends on your campaign goals, team capacity, and marketing strategy.
