We currently use Constant Contact for email marketing and are moving email sends, one-off marketing emails, and ongoing communication management into HubSpot. This includes both our own agency/company email marketing and client email marketing, so list management, segmentation, subscription types, sender domains, permissions, and deliverability need to be handled carefully.

To apply, please include: - A brief description of your HubSpot and Constant Contact experience - An example of a similar migration or email platform transition you’ve handled - How you would approach list structure and subscription types for a company managing both internal and client email marketing - Your experience with email deliverability and warm-up planning - Your hourly rate and estimated number of hours for an initial audit and migration plan We are looking for someone who can help us build this the right way from the start.
