I use Marketo as my CRM and I’d like to create a connection between a Marketo Smart List and a Google Ads Customer List, so that existing and future customers from the Smart List are automatically added to Google Ads.
How can I connect Marketo with Zapier to achieve this? Would it be better to do it via Google Sheets? Since Marketo is marked as premium in Zapier, I’d like to see it work before committing to a paid account.
