Keeping your CRM data fresh and accurate is fundamental to any sales or marketing effort. For Ontraport users, importing contacts is a core task, whether you're migrating from another platform or adding a new list of leads. At Add to CRM, we've helped countless businesses streamline their CRM processes, and we know the ins and outs of data management. We created this guide to walk you through the traditional process of importing contacts into Ontraport. While we'll cover the manual steps in detail, we also want to be upfront: we saw the frustrations and time sinks involved and built a much better, automated solution to solve them.
Before you even think about uploading a file, proper preparation is key to a successful import. From our experience, taking a few minutes to clean your data upfront can save you hours of headaches later.

The manual import process in Ontraport is a multi-step procedure. While thorough, we've observed that it can be time-consuming for busy teams. Here’s how it works:
Ontraport gives you three options for handling duplicates, which it identifies using a unique field (we recommend 'Email'):
Ontraport supports various field types, including Text, Numeric, Dropdown, and Date. It's important to format your data correctly. For example, dates in your CSV must match the date format selected in your account's localization settings. If you want to import multiple tags for a contact, they must be in a single cell, separated by commas.
Beyond the potential for human error, the manual process has limitations we've seen frustrate clients. The 24-hour review period for email permissions can delay marketing campaigns. Additionally, role-based email addresses (e.g., sales@company.com, info@company.com) are automatically imported as 'Transactional Only,' meaning you can't include them in bulk email sends. These hurdles slow down the very processes you're trying to accelerate.
