Community FAQ
Questions by product
Brevo FAQ
Does Brevo support self-hosting or is it fully cloud-based only?
Brevo is a fully cloud-based platform and does not offer a self-hosted deployment option. All data and services run on Brevo's infrastructure, so SMBs and teams must rely on their cloud environment for operations.
Community insight informed by Reddit discussions
Can Brevo be used offline or does it require constant internet connectivity?
Brevo requires an active internet connection to access its multichannel marketing features, including email, SMS, chat, and CRM. There is no offline mode or desktop client that allows editing or campaign management without connectivity.
Community insight informed by Hacker News discussions
What are the data ownership and export capabilities in Brevo for SMBs concerned about vendor lock-in?
Brevo allows users to export contact lists and campaign data in common formats like CSV. However, some deeper CRM and automation data exports may be limited depending on your subscription tier. Users retain ownership of their data but must export it before terminating service to avoid data loss.
Community insight informed by StackOverflow discussions
Are there any API rate limits or restrictions when integrating Brevo with custom applications?
Brevo provides a REST API for email, SMS, and CRM operations with documented rate limits that vary by plan. Free and lower-tier plans have stricter limits on API calls per minute and daily quotas, which can impact high-volume integrations. Higher plans offer more generous limits.
Community insight informed by Forums discussions
How straightforward is migrating existing contacts and campaigns from other marketing platforms into Brevo?
Brevo supports importing contacts via CSV files and offers some guided tools for migrating email campaigns from popular platforms like Mailchimp. However, complex automation workflows and segmentation rules typically require manual recreation due to differences in feature sets.

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.
