As their name suggests, The Influence Agency are experts in influencer marketing and they have a dedicated landing page for sustainable influencers. TIA are not a sustainable agency themselves, though, hence the lack of a sustainability policy.

How to choose the right sustainable agency for you

1. Ensure they align with your beliefs

As well as reading their ‘about us’ page and sustainability policy, check out their socials to ensure their communication style aligns with your brands’. 

2. Check their case studies

If they’re not shouting about their results, then perhaps they don’t have any results to shout about?

3. Find a specialist for exactly what you need

Especially true of small agencies – you can’t expect a small team to be masters of all areas of sustainable marketing. Understand the areas of support you need first, and then choose an agency that specialises in that area of marketing. Be wary of full-service agencies.

4. Read their reviews

Look beyond the reviews the agency has chosen to showcase. Check their Google reviews as well as reviews on agency directories such as Sortlist and Clutch.
