Need advice from Savages here on how to align a reach out strategy post a Physical event at a territory we plan to expand

After attending a HR summit few days ago, out of the leads whom we collated, we'd love to align a reach out strategy to e-meet Decision makers and pipeline deals for this/next quarter

Although intro and thank-you note driven email has been sent to many, I'd love to understand an approach that's tried and tested many a time by you

Please put in your thoughts

Thank you🙏
