Hi @Socialshine,
Welcome to the community!
I appreciate the intent of your idea, but we’re not legally allowed to remove the option to opt out from marketing emails. The people on your list will appreciate you respecting their consent, also.
One thing you could do is in the very first email of a post-purchase flow, use language that forecasts what people can expect in coming emails. Make it clear you’re there to help, the meal plan is to assist them, and you won’t overwhelm their inboxes with unnecessary marketing emails in that context. That could help you lower unsubscribe rates.
You could also consider segmenting people who are currently on your meal plans, and excluding them from receiving your marketing campaigns.
Warmly,
~ Gabrielle, Klaviyo Champion & Marketing Lead at ebusiness pros
