Hi {{first_name}},
Your trial wrapped up on [[date]]. If you didn't get a chance to fully test [[your product]], I have two options for you:
I can extend your trial by [[number]] days so you have more time to evaluate.
I can set up a 15-minute call to walk you through the features most relevant to your use case.
Either way, the data you created during the trial is saved and ready when you are.
Which would be more helpful?
[[Your name]], [[your company]]
