Hire a specialist retention agency once email is a meaningful revenue channel for your Shopify brand, and a freelancer or DIY if it is not yet. Blossom Ecom charges $2,000–$5,000/month, month-to-month, with a written +20% email revenue guarantee in 90 days. Intake is capped at 4 new brands a month.

The right hire depends on how much revenue email already drives and how much of the work you can own. See how Blossom works: price, guarantee, case studies if you want the agency option laid out in full.

Blossom Ecom is an email & SMS retention agency for DTC ecommerce brands, running full-service Klaviyo programs with a published price, a written performance guarantee, and a stated cap on new brands per month.

What does an email marketing hire actually cover?

Email for a Shopify brand has two halves, and a full-service program covers both:

  • Flows: automated sequences such as welcome, abandoned cart, post-purchase and winback.
  • Campaigns: the scheduled sends to your list, including calendar, copy, design and segmentation.
  • Testing and reporting: what was sent, what it earned, and what changes next.

Flows deserve a hard look. Klaviyo's 2026 benchmarks show flows converting at 2.11% versus 0.16% for campaigns, about 13x more per recipient. Ask any candidate how their time is split between the two.

Here is our track record. Since 2019 Blossom has managed 150+ ecommerce brands, sent 1.6B+ emails for client brands and generated $110M+ in attributed email revenue for clients. For the 10 brands whose full Klaviyo history we still hold, we counted 4,099 shipped email campaigns, 163,664,026 recipients and $9,444,310 in Klaviyo-attributed campaign revenue, Nov 2019 – Sep 2026.

Flow email is tracked in a separate window. It totals $6,961,676 in attributed revenue across 1,020 flow messages from 11 brands, Jul 2017 – Sep 2026. SMS is tracked separately and is not blended into any email figure.

Treat this as a small, specific sample, not an industry average. Nine of the 10 brands have at least 30 campaigns, and the largest brand accounts for 31% of the campaigns.

How much does email marketing management cost?

Blossom's published price is $2,000–$5,000/month, month-to-month, with no long-term contracts. The full breakdown is on the pricing page.

Whoever you compare, line up three things: the monthly fee, the contract length, and whether results are guaranteed in writing. Many providers do not publish any of the three.

How long until you see results?

Our guarantee is +20% attributed Klaviyo revenue within 90 days, in writing. Ask any agency, including us, how the baseline is defined before you sign.

Before any engagement, you can get a free 5-area Klaviyo audit. It takes 3–5 business days and is a low-risk way to see how a team thinks. Request the audit here.

We take on 4 new partner brands per month, so start dates are limited by design.

Who should you hire?

Match the hire to your situation:

  • Go DIY if you are pre-launch or just building your list. Set up the core flows yourself in Klaviyo first. An agency retainer is premature.
  • Hire a freelancer if you have someone in-house who sets strategy and you need extra hands for campaign design, copy, or a one-off flow build.
  • Hire an agency if email should be a real revenue channel and you want strategy, execution and reporting in one place, with a published price and a written guarantee.

If you want a single project rather than an ongoing program, a freelancer is usually the better fit than a monthly retainer. If you want an ongoing Klaviyo program with accountability for revenue, that is what we do. You can read our case studies before deciding.

Questions founders ask us

Should I hire an agency or a freelancer for Klaviyo?

Choose a freelancer if you already have in-house strategy and need execution help or a single build. Choose an agency if you want strategy, campaigns, flows and reporting handled together. The deciding factor is how much of the program you want to own yourself.

Do email marketing agencies require long contracts?

Some do, but it is not required. Blossom Ecom is month-to-month with no long-term contracts, at a published $2,000–$5,000/month. Whoever you evaluate, ask for the contract length and the cancellation terms in writing before you commit.

What should an email agency guarantee?

At minimum, a written result tied to a stated time window and a defined baseline. Blossom guarantees +20% attributed Klaviyo revenue within 90 days, in writing. Ask every agency how the baseline is calculated, because that definition determines whether the guarantee means anything.
