The Best Practice for adding leads to an Automation is to add them in drip mode. This prevents any blockage of your account due to a mass email.

Step 1: Select All the Leads you want to add to the workflow

• Go to Bulk Actions and Add them to Campaign in Drip mode
• To “Warm up your Email” start with adding 10 Leads a day in the first week, and add 10 more the that number each week.
• Select which days you would like emails to send.
• Select the time you would like these emails sent.
