Frequently Asked Questions
Have questions about working with us? Find answers to common questions below.
What makes Email Synthesis different from other email development agencies?
Unlike general digital agencies that offer email as one of many services, we focus exclusively on email development. This specialization allows us to master the nuances of email coding, stay current with all email client updates, and deliver superior results that generalist agencies simply can't match.
How do you ensure emails display correctly across all email clients?
We employ rigorous testing across 40+ email clients and devices using industry-leading tools like Litmus and Email on Acid. Our development approach uses battle-tested code patterns that work consistently across platforms, and we maintain an extensive knowledge base of client-specific quirks and workarounds.
Do you work with clients outside of North America?
Absolutely! While we're based in Toronto, we work with clients globally. Our remote workflow is designed to accommodate different time zones, and we've successfully delivered projects for clients in Europe, Australia, and beyond.
What's your typical turnaround time for email development projects?
Turnaround times vary based on complexity and current workload. A standard responsive email typically takes 3-5 business days from approval of design to delivery of tested code. Complex interactive emails may require 5-7 business days. For urgent projects, we offer expedited services when available.
Do you offer ongoing maintenance and support for email templates?
Yes, we offer maintenance packages to keep your email templates updated with the latest email client changes and best practices. We also provide quick-response support for any issues that arise with previously delivered templates.
Can you work with our existing design team?
Definitely! We frequently collaborate with in-house or agency designers. We can provide guidance on email-specific design considerations to ensure your designs translate perfectly to code, or we can work directly from your completed designs.
