When should I hire someone in-house for email?

When email is already one of your biggest channels and the volume justifies a full-time role. Until then, an agency covers the whole channel for less than a salary plus tools.

What makes One Mail Studio different from other email agencies?

We only do email for e-commerce, we are official Klaviyo and Omnisend partners, we work in English and Spanish across several markets, we take few accounts at a time and our monthly plans have no lock-in.

Do you work with Omnisend as well as Klaviyo?

Yes. We are partners of both, we run accounts on each and we migrate stores between them when the numbers justify it.

How we compare

Specialist agency, freelancer or in-house. What fits you

One Mail Studio is an email-only agency for online stores, an official Klaviyo and Omnisend partner, working in English and Spanish. Compared with a generalist agency you get a team that does nothing but email; compared with a freelancer, strategy, design and reporting under one roof; compared with an in-house hire, the whole channel from €550 a month with no lock-in. Below is how the four options compare, and when another one suits you better.

Honestly

When another option suits you better

We would rather tell you now than lose your trust later.

A freelancer

If your store is just starting, you send a newsletter now and then and the budget is tight, a good freelancer covers it. Come back when email has to sell.

An in-house team

If email is already one of your biggest channels and you send every day, a dedicated team can make sense.

A generalist agency

If you want one supplier for ads, social, web and email, a generalist agency is simpler to manage. You give up depth in each channel.

Questions about choosing

A freelancer works well for a young store with simple needs and a tight budget. A specialist agency makes more sense when email has to be a sales channel: you get strategy, design, copy, data and a monthly report from one team.
