1. Take time to plan - The nurture campaign will likely be foundational to your marketing program from here on out, so don't do this step halfway, get it right from the get-go! Pow-wow with posters and paper, or hog a whiteboard for a day or two and map out the entire funnel and nurture program plays in there. Get down how/where the content, the triggers, the scores, etc. all fit in. (It took a pretty big whiteboard for us!)
2. Know your tools and use them - the nurture campaign is where you can take all of the tools in Marketo and bring them together - emails, landing pages, forms and more. Once you dig in, you'll find the opportunity to use tokens, segmentation, smart lists, alerts, etc. I also am constantly grabbing data and adding it to my lead's info through the change data value flow step. As you whiteboard and plan your nurture program, get creative and try to use all of the tools at your disposal and start to weave them together in beautiful marketing synergy.
2.5 When you think you've got it all down - throw in the complex stuff that Eric is talking about - A/B testing, SMS, etc. Someday, I'd like a step where I get an alert to send a direct mailer piece to the lead.
3. Be transparent with your organization - know that what you're doing is
awesome! See if you can send the nurture emails to your fellow employees to share the awesome content with them and particularly facilitate sales-marketing fusion. Once your colleagues grasp what you're up to, they should be amazed. When you have their support, you'll be more motivated, the rest of the company will be excited for this, and your program should be more successful because your inside and outside sales team will be better prepared for the hand-off of leads.
