How to test multiple email providers

What are you using to send emails? Is it your own server, or you pay one of the biggest providers?

If you use one of the most common email marketing services, they probably have built their own ESP or use a most common one (like one of those below).

There are many that allow to integrate through API’s or use a simple SMTP connection. Just to remember a few:

• Amazon SES
• Sendgrid
• Mandrill (if you also have Mailchimp paid account)
• Sparkpost
• ElasticEmail
• Mailgun
• … many others

What is an Email Service Provider?

An email service provider is a company that offers a platform for sending and managing emails. It provides businesses and individuals with the tools and infrastructure needed to send, receive, and manage emails effectively and efficiently.

An email delivery service is a type of service offered by an email service provider that helps ensure that your emails are delivered to your target audience’s inboxes.

The service uses advanced technologies and algorithms to improve the deliverability of your emails and avoid common problems such as spam filtering and email blocking.

An email delivery service also provides reporting and analytics to help you track and improve your email performance over time. With an email delivery service, businesses and individuals can have more control over their email campaigns and improve the effectiveness of their email marketing efforts.

6 reasons to A/B test multiple email Providers

There is no right answer for everyone to the question: what is the best email provider?

Here are top 5 reasons why you should test email marketing through multiple ESP and see which one has the biggest results.

1. Deliverability:
   • Test to determine which service provider gives the best deliverability rates to your target audience’s inbox.
2. Open and click-through rates:
   • Test to find the provider that gives you the highest open and click-through rates.
3. Spam filtering:
   • Different email providers have different spam filtering systems, so testing can help you determine which one provides the best protection against spam.
4. Existing Provider:
   • If you already use an existing provider, is really simple to use their API to test against another new one.
5. IP warm-up and blacklist management:
   • Every big ESP has it’s own connections to biggest email providers (Gmail, Microsoft, Yahoo) therefore not all behave the same.
6. Pricing
   • While this is actually important, you will see that growing your email list also increases the costs with Email Marketing. Therefore you need to calculate ROI and see which one would fit your financials.

Advantages of having access to send through multiple email providers:

• doing A/B test to see which one has better deliverability (more opens, clicks and more sales)
