Couple of thoughts –
“brands” isn’t specific enough. Who is the person you help within a brand?
Go deeper than – “improve media effectiveness”.
If you have a feature (AI to pull best ads) which leads to a benefit (improved media effectiveness) what is the desire of the prospect that would lead them to take action?
– secure their jobs as ad spend gets slashed
– look like a hero in front of their colleagues
– prove the effectiveness of their work to their boss
Same thing with “understand why their ads work”. That’s a benefit. What’s the desire behind it?
One you crack the desire why people really take action your direct cold outreach and marketing will generate emotional responses.
