Newsletters
The power of emails.
MailerLite
You can control Mailerlite via API.
Setup MailerLite with your Custom Domain π
You will need to authenticate that you own the email and also the domain (with DNS).
Go to your mailerlite dashboard UI
I am using Cloudflare for that domain, and the DNS were updated automatically via UI.
There are some CName and txt records and they will be DNS only, not proxied.

Create a new form and you will get the JS to place before the </head> of your web.
<!-- MailerLite Universal -->
<script>
(function(w,d,e,u,f,l,n){w[f]=w[f]||function(){(w[f].q=w[f].q||[])
.push(arguments);},l=d.createElement(e),l.async=1,l.src=u,
n=d.getElementsByTagName(e)[0],n.parentNode.insertBefore(l,n);})
(window,document,'script','https://assets.mailerlite.com/js/universal.js','ml');
ml('account', 'some_acount_id');
</script>
<!-- End MailerLite Universal -->You can also get MailerLite working with a button, so that it opens as pop up:
<a class="ml-onclick-form" href="javascript:void(0)" onclick="ml('show', 'some_id_here', true)">Click here to show form</a>
and use it with your components, for example
<form id="simple-newsletter-form" class="input-container" method="post" action="javascript:void(0);" onsubmit="ml('show', 'some_id_here', true); return false;">
<input type="submit" value="Ready to Know?" class="ml-onclick-form" style="appearance: button; -webkit-appearance: button; cursor: pointer;">
</form>RSS

So we can pull the last video of a channel like: just take the ChannelID
curl -s "https://www.youtube.com/feeds/videos.xml?channel_id=UCPPMA8ZEusAe5dVH6PbjZFA"
#curl -s "https://www.youtube.com/feeds/videos.xml?channel_id=UCPPMA8ZEusAe5dVH6PbjZFA" | grep -oP '(?<=<title>).*?(?=</title>)' | head -5Calendar

Google ads plays well with GA4.
You could also use Umami + PostHog to track your ads.

So you will potentially need more reps.
Leads
It was not obvious to me to understand what a lead is:
The first time a marketer told me about APIFY, was quite obvious that this was not impossible.
Take into consideration that experts advice is to:
- Ads are better for mass conversion of lower ticket items
- Cold emails ~ Leads are better for higher ticket items
Funnels
Once you get leads, you want to make sure you convert them into customers.
With a funnel, you can visualize the process of converting leads into customers.
Marketing Analytics KPIs
| Rank | KPI | The One-Liner |
|---|---|---|
| 1 | Customer Acquisition Cost (CAC) | The total price tag of turning a prospect into a customer, factoring in all ad spend and overhead. |
| 2 | Customer Lifetime Value (CLV) | The total projected revenue a single customer generates over the entire duration of their relationship with your brand. |
| 3 | LTV:CAC Ratio | The “Golden Ratio” that measures the sustainability of your business by comparing a customer’s value to the cost of getting them. |
| 4 | Return on Ad Spend (ROAS) | A direct efficiency score that tells you exactly how many dollars of revenue you earned for every dollar spent on advertising. |
| 5 | Conversion Rate (CR) | The percentage of visitors who take a specific desired action, revealing how well your messaging and user experience actually work. |
| 6 | Marketing Originated Pipeline | The total value of sales opportunities that were directly sparked by marketing efforts before being handed to sales. |
| 7 | AI Search Visibility | A modern metric measuring how often and how accurately your brand appears in AI-generated answers (like ChatGPT or Google Gemini). |
| 8 | Net Revenue Retention (NRR) | The percentage of recurring revenue retained from existing customers, accounting for upgrades, downgrades, and churn. |
| 9 | Share of Voice (SoV) | A competitive metric that tracks your brand’s dominance and visibility in market conversations compared to your top rivals. |
| 10 | Lead-to-Customer Conversion Rate | The ultimate bridge metric that tracks the efficiency of your full funnelβfrom the first “hello” to the final “buy.” |
Stop obsessing over Vanity Metrics like raw page views or follower counts.
In the current landscape, if a metric doesn’t help you predict future revenue (RevOps) or understand customer intent, itβs likely just a distraction.
