Read a current issue of the poetry publication you want to submit to. Notice how its poems are formatted, and what type of work it usually publishes.
Read the publication's submission guidelines, which are typically found on the publication's website. Here is where they detail the rules, such as how you should format your poems, how many you can send at one time, and whether to send them electronically or through the mail.
Type your poem, using a traditional font, such as Times New Roman. Use a standard font size too, such as 12.
Write the title of the poem and your name near the top of the page.
Indent the poem any way you please. Poetry often has unique indentions and formatting, but make sure it is readable.
Create a header for each page of your poem that includes the poem's name, your name and contact information, such as phone number and email address.
Write a cover letter that includes your contact information -- name, mailing address, phone number and email address -- and a brief bio that mentions previous publications and awards. Don't describe the poems you're submitting, but instead include information relevant to your career as a poet.
Submit the poems through the publication's preferred method, whether mail or online. If submitting through mail, include a self-addressed stamped envelope. This is how they mail back rejection or acceptance letters.
