Personalization, without the busywork
Six ways to make every email sent from Mailchimp more relevant and easier to launch.
Personalization for each person
Send content tailored to each customer, not the same message to an entire segment.
Update content after sending
Your emails evolve in real-time, even after they’re sent. Show fresh prices, live inventory, and updated products to unopened emails.
Individually, for each subscriber.
No segments to manage
Personalize using individual behavior and current context, with no segments to build or maintain.
Live in 15 minutes
Add a generated HTML code snippet and get started, without a lengthy setup process.
Fresh content in every minute
Use up-to-date customer data and product data each time, so repeat emails stay relevant.
More value for your budget
Spend less on email marketing and keep more to invest in your business.
And more time to grow. Spend less time building and maintaining email campaigns, and more time running your business.
Why Mailchimp users don’t need Klaviyo
The Klaviyo migration trap
“Migrating to Klaviyo typically costs $5-15K and 4-6 weeks of setup time.
You lose 3 months of
optimization. Then you spend 6 months learning the platform. By the time you’re proficient, you’ve spent $25K+ and missed
two peak seasons.
With Mailchimp + Quarticon’s e-mail personalization layer, you’re optimizing on day 1 for a fraction of the cost.
You don’t need 50 CDP features
Klaviyo is built for companies that need advanced
analytics, predictive scoring, advanced segmentation logic. That’s powerful – but it’s also expensive and complex.
If your main pain point is ‘how do I send better product recommendations,’ you don’t need a full CDP rebuild
The hidden Klaviyo cost
Klaviyo’s pricing scales with your list size. A 500K-subscriber list is $1,000-2,000/month before
any professional services. Mailchimp tops out at $350.
That’s $7,800-19,200 in extra annual cost for the same email volume.
Whether you’re running a sale, launching new products, or sending reminders, up-to-date and personalized products make your emails more engaging and action-driven. AI based true 1:1 personalization and product recommendations boost conversions 3 times!
Mailchimp is already winning. It’s cheap, easy, and trusted. It’s just missing one thing: the brain to make personalization automatic. Quarticon is that brain and it costs much less than one month of Klaviyo.

Frequently asked questions
Why not just use Klaviyo?
Klaviyo is powerful, but it’s also expensive, slow to set up, and overkill for most e-commerce businesses. If you have a dedicated martech team and $20k+ to spend, Klaviyo is great. Otherwise, you’re paying for features you won’t use.
Why are Living Emails better than Klaviyo’s approach?
Klaviyo can’t do this. Here’s why:
Klaviyo’s architecture:
- Sends static emails at optimized times
- Content is segment-based (everyone in “shoes segment” gets the same content)
- Once sent, the email is locked forever
- If prices change or inventory updates, Klaviyo can’t modify unopened emails
- Your only option: resend (costs money, clunky workflow)
Our approach:
- Sends personalized emails (individual-based, not segment-based)
- Content is living – updates automatically for unopened messages
- Each person’s unopened email mutates individually based on their data + current context
- No manual resend. No additional cost. Automatic.
The result: Your unopened emails are always current, always relevant, always fresh.
Will Mailchimp ever build this natively?
Unlikely. Mailchimp is a general-purpose email platform. Quarticon is a powerfull recommendation engine specialized for e-commerce that adds personalization layer to Mailchimp’s emails. We focus on your revenue.
How is this different from Mailchimp’s dynamic content blocks?
Mailchimp allows dynamic content blocks in email templates. This is not the same.
Mailchimp dynamic blocks:
- Show different content based on pre-set rules at send time
- Example: If customer purchased shoes, show shoe products
- Content is determined when email is sent and then locked
- If inventory changes after send, Mailchimp doesn’t update unopened emails
- Static after send
Living emails:
- Show different content based on real-time data even after send
- Example: Show the exact shoes in stock right now, even if inventory changed 2 hours after send
- Content updates automatically for unopened emails
- Dynamic forever- until opened, and even after (in higher plans)
Mailchimp’s dynamic blocks are like a photo taken at send time. Living emails are like a live video feed that keeps updating.
Do I need to set up segments?
No. That’s the whole point.
Klaviyo requires:
- Define segments (high-value, browse-abandon, cart-abandoners, new subscribers, etc.)
- Build workflows per segment
- Maintain segments as they change
- Rewrite email content for each segment
Living Emails:
- Send one email
- We personalize it individually for each person
- Zero segment logic. Zero maintenance.
Segments are a workaround for platforms that can’t do individual-level personalization. We don’t need that workaround.
Isn’t resending risky with Mailchimp and Klaviyo?
Only if you’re using Mailchimp (or Klaviyo) alone. With Quarticon, data refreshes through every open and click, so your resends are always current.
Traditional resend:
- You manually resend the email (cost + effort)
- Content is still the same as the original send
- If prices changed or inventory shifted, resend shows outdated info
- Customers feel annoyed (same email twice)
Living email resend:
- You resend the original email (manual, one click)
- Content has already updated for unopened emails
- But now it’s been 2 days, so data is even fresher
- Customers see current, relevant information
- Feels like a new email, not a repeat
Resending becomes safe, automatic, and effective.
Does the product offer in the email refresh in real time?
Exactly! The product offer refreshes in real time and individually for each email recipient. Every time the user opens the email you can be sure the offer in the email content will be up to date. This helps achieve better alignment with each recipient’s current needs and, of course, positively impacts conversions.
Can I personalize for anonymous (non-subscriber) visitors?
Yes, but that’s a separate feature from Living Emails.
Quarticon’s Recommendation Engine also personalizes website experiences for anonymous traffic (non-subscribers) using behavioral tracking. But that’s on-site personalization (homepage, product pages, checkout), not email personalization.
Living emails work for anyone on your email list.
Do I need a developer?
Absolutely not! Hiring a developer for this would be overkill. It’s just two code snippets: one for your website (JS) and one for your email template (HTML). We’re confident you can do it yourself.
Can I use this with Mailchimp’s automations?
Yes. You send Mailchimp emails (via automation, segment, or manual campaign), and Living Emails adds the personalization layer on top.
How it works:
- Create email in Mailchimp (automation or campaign)
- Enable Living Emails personalization on that email adding a snippet
- Send through Mailchimp as normal
- Living email features activate automatically
No need to change your Mailchimp workflow.

- Want to personalize more? Then hire more people and plan for longer nights at the office. But should better personalization really require that?
- The number of subscribers is easy to report, which is one of the reasons for its popularity. The size of the list does not indicate its business value
- The simplest approach is to use a 3rd‑party recommendation service that generates ready-to-use recommendation data. Now available in ActiveCampaign
