When Fontdue asks your customers for their email address – at checkout, on the test fonts form, or through the newsletter signup component – it also captures their newsletter opt-in preference. By default that opt-in is just a flag stored alongside the customer in your Fontdue database. To actually send those customers a newsletter, you have a few options.
The universal path – and the one most foundries use – is a CSV export from Fontdue that you import into your newsletter service. For Klaviyo and Buttondown, Fontdue can also forward opt-ins live, so new subscribers show up in your service without a re-export.
The opt-in checkbox itself – where customers see it on your site and how to relabel it – is covered on the Customers page. This page picks up from there: getting those opt-ins into the tool you actually send mail from.
Exporting customers as CSV
CSV export works with any newsletter service. You filter the customer list to opted-in customers, download the CSV, and import it into your service of choice.
Navigate to Customers and use the Newsletter dropdown to select Opted in. The list updates to show only customers who opted in to your newsletter.
Click the menu in the top right of the toolbar and select Download CSV. The export respects your active filters, so only opted-in customers are included.
The CSV contains three columns: Name, Email, and Newsletter opt-in. Since you filtered first, every row will show true for the opt-in column.
Open your newsletter service and find the option to import subscribers from a CSV. Map the Email column to the subscriber email field and Name to the name field. The Newsletter opt-in column can be ignored.
To pick up new opt-ins later, repeat the export and import. Most services deduplicate subscribers on import, so importing the full list again is safe – existing subscribers won’t receive a duplicate welcome email or lose their place. If a subscriber unsubscribes through your newsletter service, that status is managed by the service itself; re-importing from Fontdue won’t override their unsubscribed status11Double-check this is true for your specific newsletter service before re-importing..
Direct integrations
For Klaviyo and Buttondown, Fontdue can sync new opt-ins to your account automatically, so customers show up in your service without you re-running the export. Set it up under Settings → Newsletter – the Settings reference lists the fields and the one-time bulk-sync option for seeding existing customers.
