Checklist: 12 Things to Check Before Sending Your Writing Portfolio to Publishers

Everything is ready. The samples are chosen, the covering note is drafted, and the publisher's submissions page is open in another tab. This is the point where a lot of otherwise strong portfolios go out a day too early — not because the writing isn't good, but because of a dozen small details an editor will notice in the first thirty seconds.

A portfolio is not a manuscript. It is a short, curated argument that you can do the work, in the form the publisher needs, to the standard they expect, without being difficult about it. Run the checks below before you press send.

Choose samples that answer the brief

The most common mistake isn't a weak piece of writing. It's a mismatched set. If a publisher is known for essays about place, a portfolio of three experimental flash pieces and a poem isn't a bold statement — it's a shrug in their direction.

Before you select anything, spend twenty minutes with the publisher's recent output. Not to imitate it, but to work out which of your pieces a reader of that list would actually want more of.

Then be ruthless:

• Lead with the piece you would want to be judged on. Editors often read the first sample closely and skim the rest.
• Show range without losing coherence. A longer piece, a shorter one and something in a different register is usually enough. Three to five samples is a sensible default unless the guidelines specify a number.
• Cut anything you're keeping in only because it took you a long time to write. Effort is not evidence.
• Check the opening two lines of every sample. If a piece begins with weather, a waking-up scene or a dictionary definition, rewrite the opening before it goes anywhere.

A useful test: imagine the editor reading your set alongside three other portfolios. Would yours be the one they remember because of a distinctive voice, a surprising structure, or a clear through-line? If not, swap a sample for something with more edge.

Proofread the pages nobody thinks to read

Typos cluster in the places we assume nobody looks: titles, subheadings, epigraphs, captions, the first line of the second sample, the final line of the third. They also hide in proper nouns. Check the spelling of every name, street and place before you send it to someone who might know better.

If you are submitting to UK publishers, default to British spelling and punctuation unless the guidelines say otherwise. That means colour, organise, practise as a verb, single quotation marks in dialogue, and full stops outside closing quote marks when the quoted words aren't a full sentence. Be consistent in one direction — mixed house styles look careless even when each choice is defensible.

A few passes are worth the time:

• Read the whole set aloud. Your ear catches dropped words that your eye forgives.
• Change the font and page size for one pass. Faults jump out in an unfamiliar layout.
• Read it on a phone. Half of your readers will, and so will some editors.
• Ask one other person to read the first page of each sample and tell you anything that snagged.

If you wouldn't happily read it twice, an editor won't read it once.

Watch for inconsistencies in tense and point of view across samples too. A portfolio that shifts from first-person present to third-person past without purpose can feel like three different writers. Consistency doesn't mean monotony; it means the reader trusts the voice.

Rework the bio and the covering note

Bios are where portfolios quietly undo themselves. Keep yours to roughly 50–80 words. Say what you write, where your work has appeared or been performed if it has, and one specific detail that makes you a person rather than a category. "Aspiring", "passionate about storytelling" and a list of every job you've ever held all cost you space you could use for something memorable.

Check whether the publisher prefers first person or third person, and follow it. Never list a credit you can't link to or name, and never list a publication you only submitted to.

The covering note can be three short paragraphs: who you are and what you're sending; why this publisher in particular, naming a title, series or imprint rather than offering flattery; and the practical details — sample lengths, whether the submission is simultaneous, and the best way to reach you. Sign off with your name and contact details.

For example, instead of “I am a passionate writer who loves storytelling,” try “I write short fiction about coastal towns and the people who leave them. My story ‘Low Tide’ appeared in Coastlines, and I’m currently working on a linked collection.” The second version gives an editor something to hold on to.

Format it so nothing gets lost in transit

• Send one PDF for the set unless the guidelines ask for separate files, and check that it opens properly on a phone.
• Name files plainly: Surname-Title-Sample.pdf, not portfolio-final-v3-new.docx.
• Use 11 or 12 point type, 1.5 line spacing, page numbers, and your name and email in the footer.
• Add a contents page if the portfolio runs beyond a few pages, and a word count or form note at the top of each piece.
• Avoid coloured backgrounds, decorative templates and unusual fonts that may not embed.
• If they ask for a Word document, send a Word document. Now is not the moment to improve the brief.

If you're sending through a form that strips formatting, paste a plain-text version into the body as well, with clear section breaks. Some editors read submissions on their phones during a commute; make that experience painless.

Check rights, permissions and sensitivities

Before a piece goes out, confirm you have the right to submit it. If it has been published elsewhere, check whether the publisher requires first publication rights or accepts reprints, and whether simultaneous submissions are allowed. A portfolio that includes a previously published piece without a note can look like an oversight, even when the publisher is fine with reprints.

If your work quotes song lyrics, excerpts from other books, or private correspondence, either secure permission or cut the quotation. And read for anything that could identify a real person in a damaging way. Changing a name is not always enough if the details make the person obvious.

• First publication or reprint? State it plainly at the top of the sample.
• Simultaneous submissions? Mention it in the covering note if the guidelines permit them.
• Permissions? Keep written confirmation in a folder in case an editor asks.

Run the submission mechanics like a checklist

The writing can be excellent and the submission can still fail on logistics. Treat the final send as its own task, separate from the creative work.

1. Read the guidelines one last time. Check word count, file type, sample number, and whether they want a bio, a synopsis, or a covering note.
2. Confirm the email address or form. Copy it rather than typing it. If you are emailing, use a subject line that follows their instructions exactly.
3. Attach the files before you write the email. This prevents the classic “please find attached” with nothing attached.
4. Send a test to yourself. Open every attachment on your phone and your computer. Check that page numbers, fonts and footers survived.
5. Save a copy of what you sent. Note the date, the version, and the publisher's stated response time. If you follow up later, you'll know exactly what they received.

Then wait. Do not send a revised version an hour later unless the publisher asks for one. A calm, complete submission is worth more than a perfect one that arrives in three parts.

A portfolio does not have to be flawless. It has to be clear, considerate and convincing. When you have checked these details, you can press send knowing that the work is reaching an editor in the best possible shape.
