The best email marketing tool for your business is the one that matches your audience, your content and your budget. Today's tools offer targeting, segmentation and automation that used to need a large budget, so small businesses can run campaigns that compete with much bigger brands.
Whatever your industry, customers need to know you are there and how to buy from you. Email remains one of the most direct ways to stay in front of them, because you own the list.
How Do You Choose an Email Marketing Tool?
Start with your audience, not the tool. Before you compare features, answer these questions:
- Who is your audience, and how large is your list today?
- What kind of content does your audience find most useful?
- Which emails do you need to automate, such as welcome series, abandoned carts or appointment reminders?
- Which systems must the tool connect to, such as your website, store or CRM?
Once you have the answers, it is much easier to pick a tool that fits.
What Makes a Good Email Marketing Tool?
- An easy editor that lets you build good-looking, mobile-friendly emails quickly.
- Segmentation and automation, so the right people get the right message at the right time.
- Reporting on clicks, conversions and unsubscribes. Treat open rates with caution, since privacy features in some email apps can inflate them.
- Strong deliverability and authentication support. Gmail's sender guidelines ask bulk senders to authenticate their domain with SPF, DKIM and DMARC and to offer one-click unsubscribe, so choose a tool that makes this easy.
