Hey there dola50,
Thanks for reaching out to Apple Support Communities. We understand you’re seeing a black bar on the bottom of your Mail app. We’ll be happy to help.
If you tap or swipe up on the black bar, does it bring any draft emails up? If not, touch and hold the writing pencil icon and see if any appear. If they do, complete the draft or delete it and this should help. If you have drafts on multiple accounts, follow these steps to show them:
- Tap Mailboxes in the upper-left corner.
- Tap Edit at the top of the list.
- Tap Add Mailbox, then turn on the All Drafts mailbox.
Take a look at this article for more info:

We hope this helps.
Take care.
