"I need to think it over / talk to my partner / see it in email"
These responses could be a polite decline, or reflect a genuine need to better understand and digest the value and necessity of cyber insurance. Try to learn what aspects may be causing their hesitation so you can avoid pushing general selling points and directly address the relevant issues.
Consulting a business partner or spending time evaluating significant matters such as cyber crime and coverage are understandable, valid actions. But help your client ensure that the need for discussion or consideration doesn’t slip into procrastination and avoidance; establish a plan to reconnect. Schedule a day and time for a call with the client and their business partner. This provides an opportunity to address any remaining concerns in person. In the meantime, getting the application process started can be helpful. Addressing cyber protection is a critical matter that shouldn’t be delayed.
