Community FAQ

Questions by product

ActiveCampaign FAQ

Can I self-host ActiveCampaign or is it fully cloud-based only?

ActiveCampaign is a fully cloud-based SaaS platform and does not offer a self-hosted version. All data and automation workflows run on their servers, so on-premise deployment is not supported.

Community insight informed by Reddit discussions

Does ActiveCampaign provide offline functionality or local data access?

ActiveCampaign does not support offline functionality. Since it is a cloud-only platform, you need an active internet connection to access the dashboard, automation builder, and CRM features.

Community insight informed by Hacker News discussions

What are the data ownership and export capabilities with ActiveCampaign?

You retain ownership of your data in ActiveCampaign and can export contacts, campaigns, and reports via CSV exports. However, there is no full database export or direct access to raw data outside their platform.

Community insight informed by StackOverflow discussions

Are there any API limitations I should be aware of when integrating with ActiveCampaign?

ActiveCampaign's API is RESTful and supports most CRM and automation functions, but it has rate limits (typically 100 requests per minute). Some advanced reporting and automation features are not exposed via API, requiring use of the web interface.

Community insight informed by Forums discussions

How straightforward is it to migrate from another CRM to ActiveCampaign?

Migration to ActiveCampaign is generally straightforward for contacts and basic CRM data via CSV import. However, complex automation workflows and custom fields may require manual rebuilding as there is no direct migration tool for these.

Community insight informed by Reddit discussions

Klaviyo FAQ

Is Klaviyo available for self-hosting or is it fully SaaS-only?

Klaviyo is a fully SaaS-based platform and does not offer a self-hosted version. All data and campaign management happen on their cloud infrastructure, so you cannot run Klaviyo on your own servers.

Community insight informed by Reddit discussions

Can Klaviyo be used offline or does it require constant internet connectivity?

Klaviyo requires an active internet connection to access its dashboard, sync data, and send campaigns. There is no offline mode or local client functionality; all operations depend on their cloud platform.

Community insight informed by Hacker News discussions

What are the data ownership and export capabilities in Klaviyo?

You retain full ownership of your customer data in Klaviyo and can export lists, segments, and campaign reports via CSV exports or API endpoints. However, data extraction is limited to what their API supports, and bulk export of all historical campaign data may require multiple API calls or manual exports.

Community insight informed by StackOverflow discussions

Are there any notable API limitations when integrating Klaviyo with custom ecommerce platforms?

Klaviyo's API is robust for managing profiles, events, and campaigns, but it has rate limits that can impact large-scale data syncing. Additionally, some advanced segmentation and revenue attribution features are only accessible via their UI, not the API.

Community insight informed by Forums discussions

What are the recommended migration or export paths if moving away from Klaviyo?

Migrating away from Klaviyo typically involves exporting customer profiles and campaign data via CSV or API, then importing into the new platform. Since Klaviyo does not provide a direct migration tool, you may need custom scripts to extract event data and revenue attribution for full historical context.
