See It With Your HubSpot Content
What is a newsletter builder?
Feedotter provides an HubSpot newsletter builder. It works alongside your HubSpot account and is not a replacement for it. HubSpot continues to manage your audience data, subscriptions, and email delivery Feedotter adds the content, layout, review, and testing layer that HubSpot’s native editor doesn’t provide.
What is the HubSpot newsletter builder?
The HubSpot newsletter builder refers to Feedotter’s newsletter building layer for HubSpot customers — a dedicated tool for assembling, reviewing, and testing newsletters that then send through HubSpot, replacing HubSpot’s built-in editor for content-heavy publishing work.
Can Feedotter use my existing HubSpot segments?
Yes. Feedotter connects to your content sources and targets the exact HubSpot segments you assign per newsletter.
How does the content integration work? Can it pull from my CMS?
HubSpot’s native editor is designed for basic email delivery, not for the layout flexibility, drag-and-drop content tools, or review workflow that a content-heavy publishing team needs on a recurring basis. Most publishers end up building newsletters elsewhere and pasting the result back in. Feedotter removes that workaround.
Is Feedotter suitable for HubSpot accounts running multiple publications or brands?
Yes. Feedotter supports unlimited templates, one per publication or brand, all managed from a single account. A common setup among HubSpot’s multi-brand publisher customers.
Do I still send through HubSpot if I build my newsletter in Feedotter?
Yes. Feedotter builds and reviews the newsletter; the finished issue is handed back to HubSpot for delivery through your existing HubSpot sending setup, with no change to your deliverability or list architecture.
