Why we're making this change
The legacy email builder has served you for a long time, but it has reached its limits. Layouts are rigid, previews aren't reliable, and a number of bugs have persisted despite several rounds of fixes. Maintaining two builders in parallel slows down every improvement we want to ship.
The new email builder, released earlier this year, is:
More flexible — drag-and-drop blocks, conditional content, and reusable sections.
More accurate — previews reflect what recipients actually see across clients and devices.
Actively maintained — all new features, templates, and integrations land here first.
By focusing on one builder, we can ship improvements faster and give you a single, consistent experience.
Key dates
25 May 2026 — You can no longer create new emails with the legacy builder. When you click Create a new email template, the Standard option will no longer be available — pick Visual builder (the new builder), HTML, or Text Only instead. Duplicating a legacy-builder email will create the copy in the new builder. Your existing legacy-builder emails continue to work as before.
Over the coming year — All remaining legacy-builder emails will move to the new builder. The migration is on us, and we'll give you clear notice before it affects your workspace. You don't need to prepare anything. If you'd rather migrate on your own schedule in the meantime, you can do so at any time using the steps below.
Later in 2026 — We'll migrate the default system emails (the ones FullFabric sends automatically) to the new builder, and make them editable by you for the first time. We'll announce this separately, with plenty of notice.
What you need to do
If you already use the new builder: nothing changes.
If you still use the legacy builder: you have until 25 May 2026 to create new emails there. After that, the Standard option is removed from Create a new email template, and duplicating a legacy-builder email will create the copy in the new builder. Your existing legacy-builder emails remain accessible and continue to work.
You don't need to migrate anything urgently. If you want to start moving legacy-builder emails over at your own pace, use the migration tool described below.
How to migrate an email
Open the email in the legacy builder.
Click Migrate to new builder in the top toolbar.
Confirm in the dialog. Migration is one-way — once an email is moved, it lives in the new builder and can't be reverted.
Review the result. Most emails come across cleanly; occasionally a complex layout needs a small touch-up.
Save.
You can migrate emails one at a time, or contact Support for help with larger batches.
Frequently asked questions
Will my existing legacy-builder emails stop sending?
No. Any email already built with the legacy builder will continue to work after 25 May 2026. The cutoff only affects the creation of new emails.
Can I duplicate a legacy-builder email after 25 May 2026?
Yes. Duplicate still works — but the copy is created in the new builder. This is a simple way to bring a template across next time you need a fresh version of it.
The new builder doesn't have feature X that I rely on.
Tell us. The new builder covers everything the legacy one did, and more — but if you've found a gap, we want to hear about it. Contact Support.
What happens if I do nothing?
Your existing emails keep working. After 25 May 2026, the Standard option in Create a new email template is removed — new emails are created with Visual builder, HTML, or Text Only instead. Duplicating a legacy-builder email creates the copy in the new builder. Over the following year, your remaining legacy-builder emails will be moved to the new builder — we'll let you know in advance before your workspace is affected.
Need help?
Contact Support, or reply to the in-app message. We will walk through migration with you and help you rebuild anything that didn't come across cleanly.
