Which Email Marketing Tools Have the Best Deliverability?

In email marketing, deliverability is everything. It's the measure of how successful you are at getting your emails into your subscribers' inboxes, rather than their spam folders or getting blocked entirely. You can have the best strategy, the best copy, and the best offer in the world, but if your emails aren't being delivered, none of it matters.

While your own sending practices and list quality are the biggest factors in your deliverability, the email marketing tool you choose plays a critical role. The best platforms invest heavily in their infrastructure, reputation, and tools to ensure their customers' emails have the highest possible chance of reaching the inbox.

So, what should you look for when evaluating an email marketing tool's deliverability capabilities?

1. Authentication Support: The platform must make it easy for you to set up the essential email authentication protocols: SPF, DKIM, and DMARC. These are technical standards that prove to mailbox providers like Gmail and Outlook that you are a legitimate sender who is authorized to send email from your domain. A good platform will provide clear, step-by-step instructions for setting up these records.

2. Proactive Reputation Management: The best email tools are vigilant about protecting the reputation of their sending IP addresses. They use sophisticated algorithms to monitor for suspicious activity, manage sending volumes, and maintain strong relationships with major mailbox providers. They should also have a strict compliance team that vets new customers to prevent spammers from joining the platform and harming the reputation of all other users.

3. List Hygiene Tools: A great platform will provide features that help you maintain a clean and engaged list. This includes automatically removing hard bounces, making it easy to create segments of inactive users, and providing tools for building re-engagement campaigns. A platform that helps you keep your list clean is a platform that is invested in your long-term deliverability success.

4. Transparent Analytics: You need clear visibility into your deliverability metrics. Your tool should provide detailed reports on bounce rates (both hard and soft), spam complaint rates, and unsubscribe rates. This data is essential for diagnosing any potential issues with your sending practices.
