Lemlist

Last updated on Jul 03, 2025

Lemlist is a sales engagement platform that accelerates and optimizes every interaction throughout the sales process. It is used to personalize emails on a large scale to increase your cold email outreach, automate follow-ups with your prospects, and keep campaign related emails out of the spam folder of the prospects. So, you can engage your prospects at the right time across the right channels.

You can replicate the data from your Lemlist account to a Destination database or data warehouse using Hevo Pipelines. Hevo ingests the data objects in Full Load mode. Refer to section, Data Model for the list of supported objects.

Lemlist uses an API key to identify Hevo and authorize the request for accessing account data.


Source Considerations

  • Rate Limit: Lemlist imposes a limit of 20 API calls per two seconds per API key. If the limit is exceeded, Hevo defers the ingestion till the limits reset. Read Rate Limit.

Limitations

  • Hevo currently does not support deletes. Therefore, any data deleted in the Source may continue to exist in the Destination.

  • The data is loaded in Full Load mode in each Pipeline run. As a result, you cannot load the historical data alone at any time.

  • Hevo does not load data from a column into the Destination table if its size exceeds 16 MB, and skips the Event if it exceeds 40 MB. If the Event contains a column larger than 16 MB, Hevo attempts to load the Event after dropping that column’s data. However, if the Event size still exceeds 40 MB, then the Event is also dropped. As a result, you may see discrepancies between your Source and Destination data. To avoid such a scenario, ensure that each Event contains less than 40 MB of data.
