Archive Constant Contact Campaigns

I need to archive over 1,000 email campaigns from my Constant Contact account before closing it. The ideal archive format is not specified, so suggestions are welcome. The task requires careful handling of large data sets to ensure integrity and accessibility. Experience in email marketing and data management is essential. Ideally, the archive would include: * Each campaign downloaded as **HTML** (preferred) or **PDF** * Files named using the **date and campaign subject** * Campaigns organized into folders by **year** * Images preserved whenever possible * The complete archive delivered as a **single ZIP file** Please also create an index spreadsheet with the following columns: | Date | Campaign Title | File Name | | ---- | -------------- | --------- | Finally, please explain whether you would accomplish this using the **Constant Contact API**, browser automation, or another automated method, and briefly describe your approach.
