Challenge

The agency managed email marketing for clients with growing subscriber lists and frequent campaigns.

Emails were sent consistently and on time, but engagement was declining.

Clients began questioning whether the right people were receiving the right messages. As lists grew, expectations around targeting and relevance increased as well.

Internally, the pressure was even higher. Segmentation work took too long, email software costs were rising, and mistakes became harder to avoid as the agency scaled its client base.

As a result, many of the core services they were offering started to feel fragile.

Core problem

The agency’s issues were very specific and very real.

To improve targeting, they kept creating more lists. But because their email platform charged per list instead of per unique contact, costs climbed quickly.

At the same time:

Deliverability felt weak, but the cause was unclear
Sending one campaign to multiple audiences risked duplicate emails
There was no reliable way to automatically exclude contacts from campaigns
Manual exclusions were error-prone and time-consuming
Email templates took too long to manage and were frequently rebuilt from scratch

As the client base grew, segmentation logic became harder to maintain, mistakes became more likely, and confidence in email delivery dropped.

Providing email marketing services started eating into margins instead of supporting them.

Solution

The agency switched to Email Hero inside AISQ Meteor and started implementing better, more efficient workflows.

One contact, one record. No duplicates.

First, the agency connected Email Hero to Amazon Web Services SES and imported all existing contacts needed to manage their clients’ campaigns.

With Email Hero, they only paid once per contact. So whether a subscriber appeared in one list or 20, the cost stayed the same.

This was an immediate game changer.

The biggest cost problem was solved instantly.

One campaign. Multiple audiences. No duplicate sends.

Using Email Hero’s Original + Iteration system, the agency could:

This removed one of the biggest operational risk they previously had with email sends.

The deliverability “aha” moment

Before sending campaigns, the team started using Email Hero’s built-in Email Assistant.

This was a turning point.

For the first time, they clearly understood why earlier emails struggled to reach inboxes:

These were the exact problems quietly hurting inbox placement before.

Fixing these problems before sending explained months of inconsistent results. Deliverability stopped being guesswork and became predictable.

Segmentation based on behavior

The agency was able to easily segment client subscribers based on real behavior. They defined segmentation rules using clear engagement signals such as:

As a result, subscribers segmented themselves through their actions.

Each contact received messaging that matched their current level of interest, allowing the agency to hyper-target audiences in real time without manual list updates or exclusions.

Faster template workflows

Email Hero’s templates allowed the agency to:

Campaign preparation became faster and far more consistent, saving hours every week.

Duplicate sends were eliminated completely
