An Eighth Issue: Almost Something

Agents Are the New Interns

Hi Marketer,

After the last issue, this little newsletter quietly crossed 100 subscribers. Huge thank you for reading, sharing, and replying. It means a lot. 🙏

To celebrate, I built a small gift for you: a custom GPT that answers the technical side of marketing, tracking, analytics, SEO, AI tools, and the works. Think of it as the “Engineering for Marketers Assistant.”

What’s New: Agent Mode

ChatGPT 5.0 just dropped, and the internet has been buzzing. But one feature that shipped earlier, Agent Mode, is the one I can’t stop using.

What is it?

Agent Mode turns ChatGPT from a smart responder into an AI intern with initiative. Instead of just answering questions, it can:

• Plan what steps are needed to hit a goal

• Execute those steps across websites and apps

• Loop back or adjust if something changes

• Remember progress so you don’t micromanage

Basically, it spins up its own virtual computer. It can browse, click, fill forms, run code, and even connect to your apps (Gmail, Sheets, Slack, HubSpot).

Why It Matters for Marketers

Marketing teams juggle a messy mix of research, reporting, content, and admin. Agent Mode eats that busywork.

Some examples:

• Trend research → scrape Reddit or Google News, summarise hot topics

• Content outlining → draft blog or campaign outlines in bulk

• Data extraction → pull campaign numbers and drop them into a spreadsheet

• Follow-ups → draft personalised emails from past conversations

Because it integrates with Gmail, Sheets, Notion, and Slack, Agent Mode isn’t just browsing; it’s interfacing with your actual marketing stack.

How I’ve Been Using It

I haven’t scratched the surface yet, but here’s what Agent Mode has already helped me do:

• Lead generation → pulled contacts, emails, social links

• Data scoring → auto-assigned scores to 10,000+ students in a training program

• Analytics → calculated growth metrics like GMV, CLV, per-merchant averages

• Video editing → flagged cut points and timestamps from long replays

• Brand monitoring → searched Nairaland for negative mentions of a brand

It’s already saved me hours of work in the past few weeks.

Practical Use Cases for You

Think of any repetitive, multi-step marketing task. If you can describe it clearly, Agent Mode can probably do it.

• Insights & research → competitor snapshots, sentiment analysis of reviews

• Automation & ops → dashboard generation, meeting prep, recurring reports

• Personalisation & campaigns → email follow-ups, onboarding kits, campaign inspiration

A Quick Before & After

Regular ChatGPT prompt:

“Research three competitors and suggest headline ideas for our next email campaign.”

→ Output: generic suggestions, you do the heavy lifting.

Agent Mode prompt:

“Open Company A, B, C websites. Copy recent homepage headlines, note themes/differentiators. Summarise in a table (company, headline, theme, differentiator). Draft 5 subject lines inspired by the strongest messaging. Export to Google Sheets.”

→ Output: a real spreadsheet + subject lines grounded in actual competitor copy.

That’s the difference: ChatGPT answers, Agent Mode acts.

Wrapping Up

Agent Mode isn’t perfect, but it feels like giving your team a tireless intern. Start small with one clear task, refine your prompts, and build from there.

I’d love to hear: What would you delegate to an AI intern first? Hit reply and tell me, I might try it in the next issue.
