Sending is not metered on paid plans

What Mailwarm does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Monthly-billing prices: the page has a monthly and yearly switch labelled -13% but shows no monthly figure in its text
- Whether the first-month discount applies to annual billing
Where the sources disagree
We report each version rather than pick one.
- Its pricing page shows annual-billing prices under a monthly and yearly switch, and the text gives no monthly figure.
