Selling to American customers means working in one of the largest online markets in the world, under a set of rules that differs sharply from Europe or Canada. The US uses an opt-out model for commercial email, a strict consent regime for marketing texts, and a growing patchwork of state privacy laws. This page explains how Mailpro fits that landscape, and where each of our US guides goes deeper.
The US market in three numbers
Online shopping keeps taking a larger share of American retail. According to the US Census Bureau, e-commerce reached $340.2 billion in the second quarter of 2026, or 17.1% of total retail sales, up 12.2% on the same quarter a year earlier (seasonally adjusted, Census Bureau, August 2026). Almost everyone is reachable online: DataReportal counted 324 million internet users in the United States in late 2025, a penetration rate of 93.1%, and 417 million cellular connections, about 120% of the population (DataReportal, Digital 2026).
What those numbers mean in practice is competition for attention. American inboxes are crowded, mailbox providers filter aggressively, and customers unsubscribe quickly from anything that feels irrelevant. The brands that win tend to send fewer, better-targeted messages to people who asked for them.
Compliance: what US senders must get right
Commercial email in the US is governed by the CAN-SPAM Act, enforced by the Federal Trade Commission. You do not need prior opt-in to send a first commercial email, but every message must have honest header information and a non-deceptive subject line, identify itself as an advertisement where required, include a valid physical postal address, and offer a working opt-out that you honor within 10 business days. Each non-compliant email can cost up to $53,088 in civil penalties; the FTC kept its 2025 penalty levels in force for 2026. Our guide to whether email campaigns are legal in the US walks through each requirement.
Texting is a different story. Marketing texts fall under the Telephone Consumer Protection Act (TCPA), which requires prior express written consent, and carriers only deliver business traffic from registered senders under the A2P 10DLC system, toll-free verification or short codes. Add state privacy laws such as California’s CCPA/CPRA, and it pays to collect consent carefully from day one.
In Mailpro, every campaign carries an unsubscribe link, and unsubscribed contacts are excluded from future sends automatically. Save your postal address in your template footer once and it will appear in every campaign you build from it.
Timing across the country
A 9 a.m. send from New York lands at 6 a.m. in Los Angeles, and at 3 or 4 a.m. in Honolulu depending on the season. Most US lists span Eastern, Central, Mountain and Pacific time, plus Alaska and Hawaii. If you store each contact’s state or time zone in a custom field, you can split the list into segments and schedule one send per zone, so every subscriber receives your message in their own morning.
A calendar built around American moments
The US retail year has its own rhythm. Plan ahead for:
- Thanksgiving week: Thanksgiving falls on the fourth Thursday of November (November 26 in 2026), followed by Black Friday and Cyber Monday. Our Thanksgiving campaign ideas help you stand out in the busiest inbox week of the year.
- GivingTuesday: the Tuesday after Thanksgiving is a key date for nonprofits’ year-end appeals.
- Summer holidays: Memorial Day (last Monday of May), Independence Day on July 4 and Labor Day (first Monday of September) bracket the summer season and back-to-school shopping.
- Family occasions: Mother’s Day (second Sunday of May) and Father’s Day (third Sunday of June) are strong moments for gifting, restaurants and florists.
Swiss hosting: why it matters to a US company
Most email platforms used in the US are American companies, which means the data they hold can be requested by US authorities under the CLOUD Act, wherever the servers are. Mailpro is different: we are a Swiss company, and your contact lists and campaign data are hosted in Switzerland on private infrastructure, outside US jurisdiction. Data is encrypted in transit with TLS 1.3 and is never sold or rented. For US firms with European clients, our GDPR-native setup and Switzerland’s EU adequacy status also simplify cross-border questions. Read more about why Switzerland.
