The attention line in a business letter does one job: it tells the mail handler inside an organisation exactly who should receive the document. When only one person is named, the line is simple. When a letter must reach two or more specific people at the same address, writers run into a small but real formatting problem. Most style guides address the single-recipient case in detail and say almost nothing about the multiple-recipient version.
This article covers that gap directly.
Why multiple recipients on one attention line cause problems
A standard attention line sits between the inside address and the salutation. It carries a short directive, usually the word "Attention:" followed by one name. Readers and mail handlers process it in under a second. Stack two or three names on that same line and the clarity collapses fast.
The physical problem is length. "Attention: Sarah Park and James Okonkwo and Maria Fernandez" runs long, wraps awkwardly, and strips the line of the quick visual punch it's designed to deliver. The conceptual problem is that some mail handlers read the attention line as a routing instruction for a single item, not a distribution list. A crowded line can result in the letter going to one person rather than all of them.
There's also a formality consideration. A letter addressed to three named individuals carries a different weight than a memo or an email. When you're writing formally, the person who receives the document should feel it was sent specifically to them. Multiple names on a single attention line subtly dilutes that impression.
Three approaches that actually work
Professional style practice offers three workable solutions. Choose based on the number of recipients, the formality of the document, and what you know about how the receiving organisation handles its mail.
Stack the names on separate lines under a single "Attention:" label
This is the cleanest option when you have two or three named recipients. Write "Attention:" once, then list each name on its own line with consistent indentation. Each name can carry a title or department if that detail aids routing.
Attention: Dr. Helen Marsh, Chief Financial Officer
Mr. Tom Adebayo, Head of Procurement
The label appears once. The names stack below it. Mail handlers see the list as a unit rather than a run-on sentence. This format also reproduces cleanly in both printed and PDF correspondence.
Use a group designation instead of individual names
When the letter is intended for a team, a committee, or a defined department rather than named individuals, replace the individual names with the group's title. This works especially well when you don't know which specific person will act on the letter or when the group's membership may change.
Attention: Procurement Committee
This approach keeps the line short, avoids the risk of misspelling a recipient's name, and doesn't become outdated when staff change. It's the preferred format in many formal submissions to regulatory bodies and tender panels.
Send separate letters to each recipient at the same address
When formality is high and each recipient must feel individually addressed, send a separate letter to each person. The inside address and attention line carry one name. The salutation names one person. This takes more time but signals that the correspondence was considered rather than bulk-produced. In contract negotiations, legal correspondence, and senior executive communication, separate letters are worth the extra effort.
Where the attention line sits on the page
Placement matters regardless of how many names appear. In block format, the attention line appears flush left, two lines below the inside address and two lines above the salutation. It's not part of the inside address block, and it's not part of the salutation. It sits between them, set off by the spacing on both sides.
If you use a subject line as well, the attention line comes first. The order reads: inside address, attention line, salutation, subject line, body. Don't reverse the attention line and the salutation; the attention line is a routing instruction addressed to the organisation's mail handling staff, while the salutation speaks directly to the recipient.
How the salutation changes when multiple recipients are named
Listing two names in the attention line creates an immediate question: how do you open the letter itself? The salutation must match the attention line or the letter feels inconsistent.
For two recipients, use both names in the salutation: "Dear Dr. Marsh and Mr. Adebayo." For three, the same principle applies, though "Dear Dr. Marsh, Mr. Adebayo, and Ms. Osei" starts to read as a roll call rather than a greeting. When the list reaches four or more, a collective salutation works better: "Dear Members of the Procurement Committee" or "Dear Colleagues" (in less formal correspondence).
Avoid "Dear Sir or Madam" when you know the recipients' names. It signals that you didn't bother to personalise the correspondence, which undercuts the effect of naming them in the attention line.
Copy notation as an alternative routing tool
Sometimes the right answer isn't a multi-name attention line at all. If the letter has one primary recipient and two others who need to see it, use the attention line for the primary recipient and a copy notation at the foot of the document to name the others. This keeps the routing clear, honours the hierarchy of the correspondence, and tells every reader exactly who has seen the letter.
The copy notation goes at the very end of the letter, below the typed signature line, aligned left. Format it as "cc: Tom Adebayo, Head of Procurement" with one name per line if you're copying more than one person. This is the standard approach for board reports, legal notices, and any formal correspondence where the primary and secondary audiences carry different levels of authority.
Common mistakes to avoid
Running all names onto one line with commas is the most frequent error. It creates a line that's difficult to scan and easy to misread. Printing names in a different typeface or size to distinguish the attention line from the address block is a second mistake; consistency in typography signals professionalism. A third error is omitting the attention line entirely when writing to a large organisation and hoping the inside address does the routing work on its own. In a building with dozens of staff, a letter addressed only to a company name can sit undelivered for days.
One more point worth noting: the word "Attention" should appear as a label, not as part of a sentence. "Please direct this letter to the attention of Sarah Park" belongs in the body text, not in the attention line block. The line itself is a header, not a sentence.
For multi-page letters that name multiple recipients, each continuation page header should carry the primary recipient's name rather than the full list. This keeps the header readable and consistent with how single-recipient continuation pages work.
Get these details right and the attention line does exactly what it's supposed to: it gets your letter to the right people without delay or confusion.
