Think about the 'why' of your question. What is the goal that written communication will solve for your team, in your view? This has two benefits: one, it challenges your own thinking (perhaps the underlying issue could be solved in a different way, which might be more successful); two, it gives you justification which you can use to persuade your team members. See: Simon Sinek's "Start With Why". Additionally, I've found the "Hands-on Agile" Slack group to be a great community resource for this type of team-focused Q&A.
