6 must-know best practices for your ESP migration

Choosing a new ESP

It may seem like a simple decision when it's time to pick a new ESP. After all, as long as you and your team can send, receive, and forward emails, everything's good to go, right? Not necessarily.

When choosing a new email service provider, there are several factors to consider so your business can excel. Some vital considerations include cost, features, and security. Not all ESPs are the same, and finding the ideal blend of those features will give your team the tools they need for optimal efficiency.

Here are some of the key characteristics to look for in a new ESP.

Security

Email is the central hub for business communication. Because of that, the security of your messages is essential. While your company might use third-party apps like Trello, Dropbox, and Salesforce to manage different projects, those accounts are still linked to your email address.

If hackers compromise your email address, they can also gain access to all those services. Encryption also plays an essential role in email security, with AES 256-bit providing significantly more protection than standard AES 128-bit security.

For example, when a particular employee makes financial transactions, they might be vulnerable to spoofing attacks, where hackers masquerade as a bank or tax authority. But when you implement security safeguards like Sender Policy Framework (SPF) or Domain-based Message Authentication, Reporting and Conformance (DMARC), you can avoid those types of breaches.

Cost

In the past, configuring a new email server was expensive, but today, most ESPs are cloud-based, requiring no on-site setup and capital cost. With a cloud-based ESP, the price varies depending on user count, so you only pay for what you need and can scale as your business grows.

You can still set up your own email server using various open-source scripts if you prefer, although it will still entail the substantial price of renting or owning a server and expertise to maintain. No matter what aspect of your business you're working on, it's always good to reduce overhead and increase your bottom line. That's why cloud-based ESPs are such an ideal answer.

Features

Email may seem as simple as sending a message from point A to point B, but there's much more to it. Besides typical features like an easy-to-use UI, storage space, and message size limits, there are several other factors to consider.

ESPs that provide integration with valuable tools – such as Google with Gmail, Drive, and Calendar – can enhance efficiency and offer more features for your money. These integrations provide additional avenues for your team to be productive and are a worthwhile consideration.

In fact, choosing an ESP with a strong spam filter ensures you receive essential communications only. Unwanted spam messages can clog your inbox and slow your workflow, but an effective spam filter helps prevent that. Lastly, a catch-all feature that automatically forwards all messages to a principal address gives you peace of mind that every email is read and responded to, even if addressed to a former employee.

Once you browse ESPs with the best functionality and integration and make a choice, it's essential to familiarize yourself and your team with their use. Imagine buying the latest and greatest vehicle yet not knowing how to properly use its leading-edge features. The same situation can occur when you migrate to a new ESP and aren't fully acquainted with it.

Knowing how to make the most of a new ESP’s features offers the greatest benefit to your business and helps your team smoothly work together.

6 best practices for your ESP migration

#1. Sign up for your new ESP

When creating a new account, make sure you use the same sender name and address, so your existing customers can recognize you. Here's a quick tip on how to create a personal sender name.

#2. Confirm that DKIM and SPF are set up

For your ESP migration, it’s important that both DKIM and SPF are set up with a new email IP address. This will ensure high deliverability, especially if you're looking to send emails through SMTP. (Here's more info on how to set up DKIM in case you’re curious)

We also recommend setting up your DMARC policy to protect your domain from attacks like spoofing or phishing. Start with a small volume and a more permissive setting to test it, until moving to a more restrictive setting and higher volumes.

#3. Migrate your contacts

You can do so by manually downloading them as a CSV file, or if your email provider is supported, you can automate this process using elastic.io. Always remember to migrate your bounced and unsubscribed contacts. This ensures you don't spam anyone by accident and risk having your new account blocked.

#4. Rebuild your reputation

Once you’ve officially moved to your new IP address and domain, for the first couple of weeks after migrating, break down your contact list into four portions and send one blast to one portion daily. Repeat this process for the first two or three weeks to ensure you don't trigger any spam alerts and negatively impact your sender reputation.

#5. Remember to migrate your HTML email templates

Your customers are used to receiving a certain look and feel from your emails (which you worked so hard to create), so making sure they make the move with you, is key.

Again, this can be an easy process, as you can refer to your email design system and C&P the HTML codes from your previous dashboard onto your new email provider. Once you’ve migrated all your email templates, be sure to check that all your links still work, including the unsubscribe button.

Mailjet’s email marketing solution allows you to easily create beautiful designs for your emails. If you’re using a design tool that supports HTML export, like Figma or Adobe XD, you can export your email templates in HTML format using Mailjet’s advanced editor.

#6. Give your subscribers a heads-up

Let your contacts know about the switch and ask them to add your email to their address book to help deliverability and ensure they continue to receive your messages.

If you haven't contacted your customers for a while, you may want to consider opting them in once more to ensure they still want to receive your emails. Here's some wise advice on the benefits of double opting-in.
