Email Service Provider An email service provider (ESP) enables businesses to integrate a solution for sending email, while not managing SMTP servers, blacklists, and relationships with ISPs. Developers can integrate via SMTP or an API to send necessary emails such as password resets, email receipts, and account notifications, while marketers can create, send, and analyze marketing campaigns. Using an ESP saves money and allows your engineering team to focus on building your product. It also makes it easy for marketers to send bulk marketing messages to customer segments. This can help save your business time and money. ESPs are focused on improving customer’s email communications by providing products and resources that help improve key metrics, such as deliverability and ROI on marketing campaigns. An ESP allows customers to: Manage transactional email Schedule and send marketing campaigns Analyze real-time analytics Improve email deliverability Scale their email program Benefits of using an ESP Local expertise – Receive 24/7 support to help troubleshoot deliverability issues and avoid late nights managing SMTP servers. In-house solutions are expensive – Setting up SMTP servers takes a ton of time, money, and engineering resources. Utilizing an ESP takes a ton of the mystery (guesswork) out of your deliverability and allows you to focus on your business. Improve IP reputation – When you send email from your regular email address, you risk landing in the spam folder and could affect the deliverability of your internal email. ESPs, on the other hand, are specialists that send billions of emails and have great reputations as senders. Managing and segmenting customer lists – As your subscription lists increase, it can be challenging to keep track of who joined to receive what emails. ESPs offer segmentation to ensure you are targeting the right customers with the right message. Email analytics and tracking – After clicking send on an important email campaign, you'll need to measure its success. ESPs provide customers with real-time analytics and tools that enable you to dive deep into customer engagement and ROI. Expertise Sending email is a complicated process that, when done poorly, can drain financial and engineering resources. However, when it’s done well, it can be a valuable revenue source. An ESP can help improve your company's email deliverability, content, and targeting to reduce the amount of email you need to send. This reduces your cost and can increase customer engagement. When you have issues, a good email service provider is available to provide local support. This helps your engineering team avoid late nights troubleshooting SMTP server issues and gets your email program back up and running.
