You can then send them a welcome email, a loyalty offer, or a review request — without copying and pasting anything. This turns every sale into a marketing opportunity.

See PlansMailchimp is best for small business owners who want to send email and SMS campaigns without needing a marketing team. You get a drag-and-drop email builder, ready-made templates, and automated messages that go out on their own — like welcome emails or abandoned cart reminders. It connects with tools you already use, like Shopify, QuickBooks, and Canva. Whether you run a retail shop, a service business, or a nonprofit, Mailchimp gives you the data to see what's working and adjust fast.
Square is best for US small businesses that sell in person — like retail shops, restaurants, food trucks, salons, and service businesses. It lets you accept credit cards, manage your register, track inventory, and run your whole checkout from a phone, tablet, or Square hardware. You can also use it to run payroll, set up a loyalty program, send invoices, and even access business banking. It's one of the most complete all-in-one platforms for businesses that need to get paid face-to-face.
