#1

Sagum

Best acquisition-retention link
Visit site

How they describe themselves

Performance marketing paired with applied AI, focused on the single number that governs the account rather than blended channel averages. Sagum.ai is the AI arm of Sagum, a performance marketing agency.

Why they rank here for mailchimp email brands

Connects the retention platform to paid acquisition in one model, so lifecycle revenue is attributed against acquisition cost instead of being reported as a standalone channel win. Highest channel fit because email, SMS, paid media, and the tracking layer underneath them share one owner.

For mailchimp email brands specifically

We will make the migration case both ways honestly, including the case for staying, then build genuine lifecycle automation and clean up list hygiene rather than adding newsletter volume to a program with a structural ceiling.

Chronos Agency

Deepest retention specialist
Visit site

How they describe themselves

A retention-first ecommerce agency specializing in email, SMS, and push lifecycle marketing, holding Klaviyo Master Elite partner status.

Why they rank here for mailchimp email brands

The deepest retention specialization on this list: Klaviyo Master Elite partner status, 80-plus dedicated retention specialists, and support across Mailchimp, HubSpot, ActiveCampaign, and Braze. Channel fit scores lower because top-of-funnel acquisition is not the primary practice, and the Australia and Asia-Pacific base affects time-zone overlap for US accounts.

For mailchimp email brands specifically

Mailchimp is explicitly among the platforms they support alongside Klaviyo, HubSpot, ActiveCampaign, and Braze, within the deepest retention practice here. Acquisition is not their focus and time zones are a consideration.

Things to weigh before signing

Common Thread Collective

Strongest forecast model
Visit site

How they describe themselves

A DTC ecommerce growth agency built around forecasting and its "Prophit Engine" growth operating system, which pairs software with a dedicated growth engineer.

Why they rank here for mailchimp email brands

Strong published growth methodology with retention treated as part of a forecast rather than a separate silo. Vertical depth scores lower here because the practice centers on Meta and Google acquisition, with lifecycle as a supporting discipline rather than the specialty.

For mailchimp email brands specifically

Forecast-led growth methodology with retention inside the model. Platform-level email migration and lifecycle build are not their headline capability.

Things to weigh before signing

  • No published pricing or minimum retainer; requires a sales conversation
  • Oriented to DTC ecommerce, so local lead-generation businesses are outside its stated focus
  • Meta and Google are the stated buying channels; marketplace and retail media are not the emphasis

Power Digital

Broadest capability set
Visit site

How they describe themselves

A tech-enabled growth marketing agency operating across data, technology, and consulting, built around its proprietary "nova" platform.

Why they rank here for mailchimp email brands

Covers email and SMS inside a very broad growth marketing offering with the nova platform behind it. Size fit is the constraint: the enterprise and mid-market orientation makes it a heavy fit for brands whose retention program is the main thing that needs work.

For mailchimp email brands specifically

Broad capability including email within a much larger service surface, which may be more than a platform decision and lifecycle rebuild requires.

Hawke Media

Most flexible to buy
Visit site

How they describe themselves

Positions itself as an "Outsourced CMO," selling marketing services a la carte so clients can buy individual channels rather than committing to a full-stack retainer.

Why they rank here for mailchimp email brands

Lifecycle marketing is available within the a la carte catalog. Lowest vertical depth in this lineup because retention is one of 23-plus services rather than a focused practice, and strategy connecting it to acquisition is generally a separate purchase.

For mailchimp email brands specifically

A la carte purchasing works well for a scoped project such as an automation build or a migration, without an ongoing retainer.

Things to weigh before signing

  • No published pricing; requires a sales conversation

How to choose a mailchimp email agency

Many ecommerce brands are on Mailchimp because they started there, not because they chose it for selling products. It is a capable email platform with a long history, and it was built primarily around broadcast communication rather than around ecommerce behavior. If your program is mostly newsletters and your automation is a welcome message, that is usually a symptom of the tool shaping the strategy.

The first honest question any agency should raise is whether the platform is your constraint. Deep product-behavior segmentation, granular ecommerce automations, and revenue attribution per flow are areas where purpose-built ecommerce platforms have moved considerably further. Sometimes the right answer is a migration; sometimes the platform is fine and the program is simply underbuilt. An agency that will not examine that honestly is likely to sell you effort against a ceiling.

If you stay, the leverage is in list hygiene, deliverability, and building genuine lifecycle automation rather than sending more newsletters. When weighing the five agencies above, ask who will assess the platform decision on its merits, including the case for staying, rather than defaulting to whichever answer suits their service mix.

What actually separates a good mailchimp email agency from a bad one

An honest assessment of whether to migrate
Migration is disruptive and sometimes unnecessary, and staying is sometimes a false economy. Ask the agency to make the case both ways for your specific situation, including what capability you are actually missing and what it is costing, rather than accepting a general recommendation.
Lifecycle automation beyond a welcome email
Abandonment, post-purchase, replenishment, and winback sequences are where durable email revenue comes from. Ask which of these currently exist, which the platform can support well, and which would require workarounds, because that answer is also input to the migration question.
List hygiene and deliverability
Long-standing lists accumulate dead addresses, role accounts, and disengaged subscribers that drag down sending reputation. Ask what proportion of your list has engaged in the last six months and what their policy is on sunsetting, since cleaning a list usually improves results even as it reduces the number you report.
Segmentation tied to purchase behavior
Segmenting by product category, purchase interval, and value produces materially better results than sending everything to everyone. Ask what segmentation is realistic on your current setup and what it would take to get further, in the platform you have.

How we scored this list

Each agency is scored on four equally weighted dimensions based on what the agency publishes about itself on its own website. Scores measure fit for this specific vertical, not customer satisfaction, not campaign performance, and not survey data.

Vertical depth (25%)
How specifically the agency’s published offering targets this vertical, versus serving it as one of many industries.
Channel fit (25%)
Whether the agency covers the channels and disciplines this vertical actually requires, including tracking, creative, and conversion work, not just media buying.
Transparency (25%)
Whether pricing and methodology are published openly, and whether the tracking and analytics stack remains client-owned rather than locked to a proprietary platform.
Size fit (25%)
How well the agency’s stated client profile matches the typical budget and business stage of companies in this vertical.

What this list is not

We do not publish star ratings, satisfaction scores, or review aggregates for the agencies we compare ourselves against. We have not audited their client results. Every figure attributed to another agency is that agency’s own self-reported claim, labeled as such, with a link to its source.

Frequently asked questions

Why is Sagum ranked first on a list Sagum publishes?

Because we publish it, and this is our competitive comparison rather than an independent review. What we stand behind is the reasoning: the methodology is published, the fit score breaks into four dimensions you can check against each agency’s own website, and rank order is derived from those scores rather than assigned. Where a competitor genuinely leads a dimension we say so in their entry. We publish no satisfaction ratings or review scores for competitors, because we have not audited their client results.

Should we migrate off Mailchimp?

It depends on what you are actually blocked on. If you need deep product-behavior segmentation, granular ecommerce automations, and clean per-flow revenue reporting, purpose-built ecommerce platforms are further along and migration may be worth the disruption. If your program is mostly underbuilt rather than platform-limited, migrating will not fix it and you will lose months. The honest test is naming the specific capability you are missing and what it costs you.

What does a migration actually involve?

Rebuilding automations, remapping segments, re-establishing sending reputation on new infrastructure, reconnecting store data, and accepting a period where performance is unsettled. It is a genuine project, not a data export. That is precisely why it should be justified by a specific capability gap rather than by a general sense that another platform is better.

Why has our email revenue plateaued?

Most commonly because the program is broadcast-heavy and automation-light. Newsletters reach everyone regardless of where they are in a buying cycle, so returns diminish as the list fatigues. Lifecycle automations reach people at moments of intent and compound instead. A plateau also frequently indicates deliverability erosion from sending to a large disengaged segment, which suppresses reach invisibly.

Is a large list an asset if most of it never opens?

Only partly, and the inactive portion is actively harmful. Disengaged subscribers depress engagement rates, which mailbox providers use to decide whether your messages reach the inbox at all, so a bloated list can reduce delivery to the people who do want to hear from you. Sunsetting genuinely dead addresses usually improves revenue while making your headline list number smaller.
