What Drives Price

Weight and size are the largest price levers, followed by service level and the presence of tracking or insurance. Letters that exceed standard dimensions or weigh more than an ounce typically see incremental increases. Destination country processing times and carrier choices also influence total costs for U S to Ireland mailings.

Ways To Save

Choose standard delivery over expedited options when timing is flexible to reduce costs. For smaller or lighter letters, ensure you stay within one ounce to avoid surcharges. Bundling multiple items in a single larger mailer is often less expensive than sending separately, if allowed by postal rules.

Regional Price Differences

Prices vary by origin region in the United States, with metropolitan hubs sometimes showing slightly different handling or service surcharges compared to rural origins. In general, expect small deltas of ±10–20% between major regions.
