The Work

Sinch content has to make complicated technology clear, accurate, useful, and trustworthy across markets, audiences, products, and business units.

That’s why Sinch has continued turning to Blue Ivory for content support across its broader brand ecosystem — including the main Sinch brand, Email on Acid, Mailgun, and Mailjet.

Our relationship with the company began years ago and has continued to expand as Sinch’s teams handed Blue Ivory increasingly complex work across U.S.- and Sweden-based groups. 

We’ve supported content for multiple business units, product lines, and audiences, helping translate technical communications topics into clear, credible content for marketers, developers, deliverability experts, and enterprise decision-makers.

The work has covered a wide range of subject matter: email strategy, deliverability, customer communications, developer-focused messaging, product education, campaign best practices, and the evolving ways businesses reach customers across email, SMS, messaging, and other channels.

Just as importantly, the relationship has grown because the quality has held.

As Sinch’s director of content marketing, Bea Redondo, put it:

“Blue Ivory is, by far, the best content agency I’ve worked with.

I’ve been working with Luke and his team for over five years. Over that time, we’ve gradually handed them more complex work, because the quality has always held. Our product is genuinely complicated, and they’ve never struggled with it. Give them a strong brief and they deliver.

I know I can trust them because they work with writers our team has known and admired for years. When an agency is attracting that kind of talent, you know they’re doing something right.

They’re also just easy to deal with, which sounds like a low bar but honestly isn’t.”

The result: a multi-year enterprise content partnership that continues to expand across the Sinch ecosystem because Blue Ivory can understand complex products, earn stakeholder trust, attract top-tier talent, and deliver high-quality work without making the process harder than it needs to be.

Key Advantages

  • Enterprise-level content partnership. Blue Ivory has supported Sinch across multiple brands, business units, and working groups, including both U.S.- and Sweden-based teams. That kind of relationship requires more than writing ability — it requires trust, consistency, adaptability, and strong cross-functional communication.
  • Complex technical topics made clear. Sinch’s products span communications infrastructure, email, messaging, voice, verification, and customer engagement. Blue Ivory helped turn genuinely complicated subject matter into content that different audiences could understand and act on.
  • A relationship that kept expanding. Sinch gradually handed Blue Ivory more complex work because the quality stayed consistent. That progression is one of the strongest proof points in the portfolio: the more demanding the assignments became, the more valuable the partnership proved to be.
  • Support across the Sinch ecosystem. Our work has touched the main Sinch brand as well as Email on Acid, Mailgun, and Mailjet — giving Blue Ivory unusually broad familiarity with Sinch’s audience, products, acquisitions, tone, and business priorities.
  • Trusted talent and editorial judgment. Sinch trusted Blue Ivory not only because of the finished work, but because of the people behind it. We brought experienced writers and editors to the relationship, including hiring full-time talent known and respected by Sinch’s own content team.
  • Global collaboration. Working across U.S.- and Sweden-based groups required Blue Ivory to adapt to different stakeholders, working styles, product priorities, and regional expectations while keeping the work consistent and easy to manage.
  • Technically fluent marketing content. Blue Ivory brought the right blend of technical curiosity and marketing judgment — enough depth to understand the product, enough editorial discipline to make the content useful, and enough strategic sense to keep it tied to business goals.
  • Low-friction execution. For a company as large and complex as Sinch, being easy to work with matters. Blue Ivory’s process gave stakeholders confidence that a strong brief would turn into a strong deliverable without endless hand-holding, back-and-forth, or unnecessary complexity.
