Entry paid plan $12/month (billed annually) Team Plan: $120/month (per user)
Mid-tier/pro plan Not applicable Business Plan: Contact Vendor for Pricing
Solo monthly cost $1/month (paid annually) $120/month

Mailin's pricing model is more budget-friendly, offering a free plan with limited features and a paid tier at $12 per month billed annually.

This feature is especially beneficial for creators who need to manage content ideas, project timelines, and collaboration with occasional contributors efficiently.
