Mailchimp email marketing agency

Stop sending everyone the same email. Start sending the right one.

Batch-and-blast email is dead. Your subscribers know when they are receiving the same message as 40,000 other people. Redefine builds Mailchimp automation systems that segment your list, trigger flows based on behavior, and send each subscriber the email that matches where they are in their journey, at the moment they are most likely to buy.

The batch-and-blast problem

One list. One email. Sent to everyone. That is why your open rates are 18%.

The difference between a 18% open rate and a 36% open rate is not the subject line. It is whether the right subscriber receives the right email at the right moment. Here is what both approaches look like in practice.

Merlette
The Challenge
Merlette required a modern e-commerce experience that balanced luxury aesthetics with high conversion performance. Key challenges included improving usability and accessibility, securing customer data and transactions, optimizing mobile and web performance, and personalizing the customer journey to increase engagement, loyalty, and repeat purchases.
The Approach
Email marketing automation was built as a complete lifecycle system targeting every stage of the customer journey. Welcome flows, abandonment recovery, post-purchase sequences, and win-back campaigns were configured and connected to customer behavior data, enabling personalized messaging at scale without manual effort.
The Result

  • Improved user experience and interface design increased conversion rates, customer satisfaction, and brand loyalty across the store
  • Secure payments and optimized performance reduced fraud risk and positioned Merlette as a high-performing luxury ecommerce brand
Email maturity model

Most brands are stuck at Level 2. Redefine takes you to Level 4.

Email marketing maturity is not about sending more emails. It is about sending fewer, more relevant emails that generate more revenue per subscriber. Here is where most brands are, and where you can be.

1
Collect emails. Send nothing.
A subscribe form exists. No welcome email. No automation. Subscribers join and hear nothing for weeks.
2
Batch and blast promotional emails
Monthly promotional sends to the full list. 18% open rate. High unsubscribes. No segmentation. No automation. Most brands arrive here.
Where most brands arrive
3
Basic automation plus some segmentation
Welcome email configured. Cart abandon running. List starting to segment by engagement. Open rates improving to 28 to 32%.
4
Full lifecycle automation plus behavioral segmentation
All flows live and optimized. Campaigns segmented by purchase history and engagement. 36 to 42% open rates. Email drives 40 to 50% of revenue. Deliverability protected.

Having Mailchimp installed is not the same as having an email marketing system. Most brands have a subscribe form, a basic welcome email, and monthly promotional sends. That generates approximately 18% open rates and modest revenue from email. A properly configured Mailchimp account has 5 to 8 automation flows running simultaneously, behavioral segmentation across your campaigns, deliverability monitoring, and A/B testing running on every major send. The difference in revenue per subscriber between a basic setup and a full system is 8 to 12x.

Mailchimp handles everything most ecommerce brands need at the levels our clients are at. Welcome series, abandoned cart, post-purchase, win-back, browse abandonment, and segmented broadcasts are all available in Mailchimp at standard pricing tiers. Where Klaviyo has an advantage is in deep integration with headless ecommerce setups and in predictive analytics for larger lists (100K plus subscribers). For brands with a standard Shopify or BigCommerce store under 100K subscribers, Mailchimp is capable of achieving the same email revenue results as Klaviyo when configured correctly. We also offer Klaviyo as an alternative: see our Klaviyo email marketing agency page for details.

Welcome series flows start generating revenue from day one: every new subscriber enters the flow immediately. Abandoned cart flows show recoveries within the first 48 hours of going live. Win-back flows work on your existing database and start recovering lapsed buyers within the first week. Most clients see measurable email revenue increase within 2 weeks of their flows going live. The full impact, especially on campaign broadcasts that replace batch-and-blast sending, builds over 30 to 60 days as segmentation data accumulates.

Both models work. A one-time setup engagement delivers all automation flows, segmentation configuration, and campaign templates, then hands off to your team with clear documentation. An ongoing management engagement adds monthly campaign execution (planning, writing, segmenting, and sending your promotional broadcasts), weekly performance reporting, continuous A/B testing, and deliverability monitoring. Most clients start with setup and move to ongoing management once they see how much more revenue the campaigns generate with professional management.

Email automation works effectively from around 500 subscribers. Below 500, the data volume is thin and A/B tests cannot reach statistical significance. The welcome series, abandoned cart, and win-back flows run on individual subscriber behavior and work well even on smaller lists. What requires a larger list (10,000 plus) is sophisticated segmentation across your broadcasts. We assess your current list size and engagement quality during the audit and tell you exactly what is achievable at your current volume.

Is this the right engagement?

Is a Mailchimp email marketing agency the right fit right now?

Right fit if
You have at least 500 email subscribers and send at least one email per month
Email generates less than 30% of your revenue but your open rates suggest the audience is engaged
You are sending the same promotional email to your full list every time you have something to announce
You have no abandoned cart flow, no welcome series, or you have them but they were set up without expert input
You want email to become a primary revenue channel rather than a secondary one
Your team does not have bandwidth to manage email marketing alongside everything else
Probably not the right fit if
You have fewer than 500 subscribers and no plan to grow your list in the next 90 days
You need someone to write all your email content from scratch every month: our focus is strategy and automation, not ghostwriting
You already have a dedicated in-house email marketer who manages all flows and campaigns full-time
Your Mailchimp account is already at Level 4 or 5 in the maturity model above: a setup engagement would not add value
You have a business-to-business product with a 6-month enterprise sales cycle: email automation for business-to-business long-cycle sales is a different discipline
You plan to migrate from Mailchimp to Klaviyo imminently: we can help, but see our Klaviyo agency page for that work specifically
