Which Is The Best SMTP Service Provider?

When choosing the best SMTP service provider for your needs, you don’t have to choose one from the options listed above. Pepipost, Mailjet, Moosend, Pabbly and Mandrill are just some of the many other SMTP service providers available. Having so many choices can make it difficult to select the one that best meets your business needs.

Take the three following items into consideration when evaluating SMTP services – Email deliverability, Scaling, and Pricing. Most of the platforms already discussed in this article have high email deliverability, and they can be scaled to send millions of emails daily.

Smaller sites and companies can go with SendGrid or SendinBlue. Pricing becomes a more important factor if your sending needs are larger. The SMTP provider you work with should have trusted technical support and scalability with pricing that’s very competitive.

Amazon SES is the obvious choice if you have the technical knowledge, as paying $0.10 for every 1,000 emails is a very cost-effective solution.

Please take into consideration the features that you need from the SMTP provider and their pricing options. Most of them offer detailed pricing plan summaries with features that each plan offers, so you can easily choose one that fits your needs.
