A powerful email service provider built with your business in mind

That’s what you need if you want your email marketing campaigns to be successful. Email service providers power your marketing efforts and ensure your hard work doesn’t go to waste. Push through the fear of hitting “send” and make it to the inbox with the right email service provider by your side.

What are email service providers?

Commonly known as ESPs, they’re one of the most powerful pieces of software in your sales and marketing tech stack. Send thoughtful, well-designed emails, create personalized email messages, and create a solid, repeatable marketing strategy designed to build your business — and make customers happy.

How to find the best email service provider

Today, email is still the best channel to reach your audience where they are. Whether you’re creating bulk email marketing campaigns or responding to user-initiated requests, you want to make sure you’re sending emails from an ESP that has your needs in mind.

Some small businesses start off trying to send marketing and transactional emails from free email services like Gmail, Yahoo Mail, Zoho Mail, GMX Mail, or Hotmail. With these free email get what you pay for. They have daily email send and storage limits —Google and G Suite is set at 500 — making it challenging for marketers to use these email accounts for campaigns.

To communicate confidently and consistently with your customers no matter what email clients they use, you need an email service provider to use in tandem with your personal email account.

Mailgun’s cloud-based infrastructure scales with you so you can worry less about email storage, SMTP servers, and storage space. But it’s Mailgun’s RESTful API that sets us apart from other email service providers. Our system seamlessly integrates into your web application or mobile app so you can have your company’s messaging protocol up and running in no time.
