The 10 Best SMTP Service Providers for Email Marketing
Are you confused and looking for the best SMTP service? We've hand-picked some good SMTP service providers to improve transactional and marketing email deliverability.
How Do You Know if an SMTP Service Is Good?
One of the most common problems with email marketing is that there’s always the possibility of ending up in spam. Sending emails through the usual email service providers such as Gmail only increases this possibility. The best way to stay spam-free is to use SMTP services.
A Simple Mail Transfer Protocol (SMTP) server is an application that handles all the aspects of sending emails. Its main purpose is to deliver your emails on time and make sure they go straight to the customer’s inbox. SMTP mail services are good for both marketing and transactional emails — they allow you to upload your contact database, segment your contacts, edit your email layout and work with HTML, and select the sending time and date.
Now, let’s assess 10 best SMTP service providers and try to find the perfect one for you.
SMTP.com page for marketers
SMTP.com calls itself the best email service for WordPress. That's because it helps you avoid ending up in spam, send emails quickly, and can handle really high volumes. The plans range from up to 50,000 emails to over 1,000,000 emails per month, that’s more than enough for any type of company. And this is why over 100,000 enterprises enjoy working with SMTP.com.
The server offers a custom API or a platform for those who require personalized email infrastructure. The emails are sent with good uptime performance and, as many people claim, the service boosts deliverability and makes the whole process easier and more secure. SMTP.com allows you to use both shared and dedicated IPs, and get your emails delivered with over 99% uptime.
The Integrated Reputation Defender feature based on big data vigorously monitors your email list’s condition and protects your domain and IP reputation among ISPs by dampening bad addresses in your campaigns from hard and soft bounces. With this technology, your rates for delivery and inbox placement gradually improve over time.
Sendinblue helps organize your email marketing
One of the best SMTP mail servers offering mass email marketing, a text and block email editor with a template gallery, campaign statistics, and some tools for marketing automation. Sendinblue also allows you to send transactional emails — for example, order placement notifications or registration confirmations.

SendinBlue pays special attention to the security of information uploaded by users. The measures taken include a multi-level firewall and a reliable antivirus app that checks if the emails have any viruses. When transmitting encrypted data, HTTPS, and SSL technologies are used.

It’s a fairly cheap SMTP service and the client pays only for what they actually use.

If you email from an application hosted on Amazon EC2, the first 62,000 emails sent each month are free.
So What Should You Choose?
You can make a decision by answering the questions below. They will help you determine the best SMTP service for you and cast aside those that do not fit you.
Specify your requirements. Do you need integration with CRM? Do you want a dedicated IP address? Will you need triggered emails or automated email series, or both? What are your price limits for a month or a single campaign? What are your marketing plan metrics?
Think ahead of time. What will be important for your company as it grows? Are you going to need cross-channel communications? Will you need integration with Google Analytics or a similar service?
Don’t pay too early. Use free plans or trial periods to test a couple of mass mailing services on a small part of your list. Almost all services have either one or the other. Those that have neither are most likely to have a demo, at least.
Most companies have long been trying not to just find a random solution for one task only — they want to put together as many tools as possible so that they can aim at several targets at once. Therefore try to choose flexible solutions that can be integrated with all the channels and systems that are important to your business. And the services above introduce SMTP best practices to their platforms to make clients’ experience better with each interaction.
