"I searched through a number of forums and word of mouth on the web, and their name consistently came up. They have been in business longer than any email marketing company that I can remember talking with."

Our company needed to revamp our entire email system for our main brand of bicycles, Sixthreezero. We hired InboxArmy to build out new automated flows, post purchase email flows, marketing campaigns, and anything else we could come up with to stimulate our sales. I worked with the director and his designers to develop the emails that would connect with our target market. InboxArmy managed me, I literally had to keep up with how fast they work.

Immediate increase in revenues, our return customer conversion rate increased by roughly 50%, and our open to click rates all increased. The ROI was about 26 to 1. Zero complaints, our resources were not wasted hiring InboxArmy.

Ecommerce Email Marketing Case Study

Maven Lane

Maven Lane had strong products, a premium brand, and an email program generating almost nothing. No automated flows. No campaign calendar. Sends going out without a strategy.

The rebuild was structured around how their customers actually shop for furniture, longer consideration windows, concerns around quality and delivery, and a price point that requires more reassurance before a first purchase. The welcome series, abandoned cart recovery, and post-purchase sequence were all built around those realities.

Revenue from automated lifecycle flows:

$641,826

Kinship

“InboxArmy came recommended through our head of growth marketing- deciding factors included budget, experience in the space, and immediate availability.”

It’s rare to see an external vendor so invested in our success. And yet, that’s exactly what we have experienced with InboxArmy. Each member of the IA team is always hyper-focused on the success of our campaigns. Right from Day 1, these guys have worked hard to set up streamlined workflows, design and code world-class emails, and even coordinate with our developers to set up the proper data architecture to trigger emails. If that’s not all, they consistently go above and beyond the regular scope of work to address problems and optimize every campaign. We hardly ever feel the pain of any issues because these guys are there to proactively resolve them as early as possible. Amazingly, nothing ever seems to faze them. At one point, we switched ESPs quite suddenly, but the IA team took it in in stride and none of our campaigns were affected. Very impressive indeed!

Compare Your Email Program Against These Retention Benchmarks

Use these directional indicators to spot where your retention program may be losing ground. Every brand and audience behaves differently; these aren't guarantees, but they're useful reference points.

Benchmark What Well-Run Programs Tend to Show What It Often Means When You're Below
Automation & Retention Flow Revenue Automation revenue tends to account for 30–40% of total email revenue in well-run lifecycle programs. Below 20%? Usually incomplete flow coverage or cart sequences without escalation logic.
Welcome Series Conversion New subscribers typically convert to first-time buyers within 72 hours of opt-in. Leading with brand story before the subscriber decides they're interested.
Abandoned Cart Recovery Recovery typically requires at least 3 emails with escalating urgency + 1 offer step. Single cart email = recoverable revenue uncollected daily.
Post-Purchase Retention The window between first and second purchase is the highest-leverage moment in lifecycle marketing. Flow ending at order confirmation ≠ retention program.
Deliverability Health Open rate swings of 10–15+ points between comparable sends (without content changes) warrant investigation. Usually an infrastructure-level issue, not creative.
List Health Active acquisition should grow (not flatten/decline) the list. Flat/declining list = high unsubscribes + poor new subscriber engagement.
Attribution Accuracy ESP revenue and ecommerce platform revenue should reconcile. When they don't, optimization decisions are built on unreliable data.

“Revenue per email sent up more than 15%, Bulk email sends up from 1 per week to 3-4 per week, Trigger/automated campaigns from 2 to over 13, producing over 20% of program revenue”

We found them through an online search and selected them because of high ratings, good value for cost and no unneeded extras. InboxArmy is responsible for managing the segmentation, creative coding, scheduling, and execution of all bulk, targeted, and automated email campaigns for GoodwillFinds. Additionally, they help manage our instance of Salesforce Marketing Cloud. Campaigns and workstreams were always delivered on time and they have been very responsive with emergent requests that arise due to changes in business conditions.

They seem to be working around the clock. It's amazing how much they get done while I'm sleeping!

    “We looked at 16 different agencies, interviewed 8 of them and selected InboxArmy as number 1 pick.”

    We hired InboxArmy to redesign Salesforce Marketing Cloud emails. The goal was to create a new master template that matched branding using industry best practices. After we signed the SOW, we had a couple discovery calls, submitted our brief and branding document. Once we were on the same page, InboxArmy did design in batches, we had 3 rounds of reviews and once all was finalized IA coded and implemented the templates for us in MC.

    During discovery calls, members of IA were present (covering design and coding). After that we always communicated with our representative, Charlie. Being able to understand branding and our needs, design capabilities, coding pace, responsiveness and always willing to go step beyond for this project.

    Felt like IA and we were on the same team.
