Frequently Asked Questions

How do I connect Mailsac and buttondown?

Sign up for a free viaSocket account, then authorize both your Mailsac and buttondown accounts. From there, pick a trigger in one app and an action in the other. Your first workflow can be live in under five minutes.

Does this integration work in real time?

Yes. viaSocket uses instant triggers where available, so data moves between Mailsac and buttondown as soon as the event happens. Scheduled polling triggers run at a maximum interval of 15 minutes.

Can I control which data gets sent from Mailsac to buttondown?

Yes. You can map specific fields, apply filters to skip records that do not match your conditions, and transform values before they reach buttondown. No coding required.

Can the integration run in both directions?

Yes. You can set up a workflow where Mailsac triggers actions in buttondown, and a separate workflow where buttondown triggers actions in Mailsac. Both run independently and in real time.

What happens if a step in the workflow fails?

viaSocket logs every run so you can see exactly what succeeded and what failed. Failed tasks can be retried from the dashboard without re-configuring the workflow.

Is viaSocket free to use?

Yes, there is a free plan that covers basic workflows between Mailsac and buttondown. Paid plans unlock higher task limits, faster polling, and advanced features like multi-step workflows and conditional logic.

Do I need to know how to code to set this up?

No. The entire Mailsac and buttondown integration is built through a visual, point-and-click interface. Code blocks are available if you want them, but they are never required.
