How do you choose the right email provider?
Now that you have an amazing list of 10 email service providers, it’s time to understand how to choose the best one for your business.
The right service provider should meet your unique business’s needs and make your marketing efforts more successful. You’ll want to choose the most appropriate email service provider according to your business’s size and functions, minimize the time it takes to set up campaigns, and streamline daily operations.
Let’s look at what you need to look out for as you shop around:
Features
When doing a side-by-side analysis of email providers, think of the features that line up with your goals and are within your budget.
Below are some key features that you can prioritize:
- Deliverability: Look for ESPs with a strong track record of high deliverability rates and good sender reputation.
For instance, ProtonMail has a high deliverability rate of 74.98% (average spam rate-12.29%); on the other hand, Outlook has a deliverability rate of just 46.54% (average spam rate-31.47%)
- Email list management: Your email provider should provide tools for managing your email list, such as segmentation, contact management, and labeling.
For instance, Zoho mail allows you to create mailing lists to group contacts together based on various criteria.
- Email Templates and automation: Look for a platform that offers customizable email templates and automation features to help you create engaging emails in seconds.
For instance, Gmail offers Gemini AI, which lets you write emails through AI. You just have to provide a prompt on what the email is all about, and the AI will do the magic.
- Security and Compliance: Ensure your service provider follows best practices for data security and complies with email marketing regulations such as GDPR and the CAN-SPAM Act. Also, look for data encryption, two-factor authentication, and alias addresses for better security.
For instance, Outlook, AOL, Gmail, and Zoho Mail are all GDPR and CAN-SPAM Act compliant.
Ease of use
Let’s face it. Email marketing, especially automation, is quite a complicated affair. That’s why you need an email provider that’s easy to use. You don’t want to be dependent on your technical team (if you have one) or look for solutions online to learn how to use the platform.
Here are a few questions you can ask for:
- Are the specified features easy to use?
- Is the platform optimized for mobile and responsive design?
- Is the interface well-organized and intuitive?
- How long is the learning curve?
Integrations
When it comes to marketing, email marketers use an average of 5 apps to power their marketing efforts. This includes everything from analytics to automation and everything in between.
Data integration involves linking various systems, including web analytics, CRM platforms, content management systems, and eCommerce platforms, into a unified system. It is crucial to have top integrations available so you can use the data for segmentation, personalization, and scaling your outreach efforts.
For instance, ProtonMail, ZohoMail, Gmail, Yahoo Mail, and Outlook offer integration capabilities with various third-party applications through IMAP/SMTP support.
Scalability
Assuming you’re looking for a free email service provider, you probably have a mailing list of less than 2000 subscribers. The question is, will your ESP have the capability to send emails when your mailing list explodes to over 20,000 or 200,000 subscribers?
Your service provider should be able to meet your needs both now and in the future. Pay attention to service providers that are evolving their services to fit better people’s needs versus those that are staying the same.
Which ones are the best for cold outreach?
If possible, when choosing your email provider for cold emailing, it’s vital that you don’t go with a free option like a free personal Outlook or Gmail account.
The reason to avoid them is that if there’s any issues, you’ll quickly get blocked from using them, as high-volume outreach is against the terms of these free accounts.
However, if you still want to go a free service provider then the following options stand out based on their features and overall effectiveness:
