Scaling Email to SMS for Enterprise: Challenges and Solutions

 While going from 1 million emails sent each month to 2.5 million, or from 5 million to 10 million, are fantastic milestones, other factors also come into play. The amount of time you must spend on your email software and the various messages you are sending will increase as your email traffic rises. Infrastructure, analytics, email best practices, changes to the email ecosystem, and legal compliance will all grow to be major concerns.

In order to make sending large volumes of emails easier, SendGrid has sent more than 1 trillion emails and now collaborates with over 45,000 paying clients. When it comes to email knowledge, we are the most dependable and trustworthy option since we invented email infrastructure. We will assist you in developing a sound, long-term approach if you want to send a lot of email.

This manual will walk you through the procedures you must follow in order to expand your business and email campaign properly. We'll also list typical blunders that other senders have made so you can steer clear of them on your way to success.

We've also included a checklist that you can print out and keep handy. This will enable you to remember these scalability requirements as you expand.

Lower Volume Protections

There are a few things you should do as soon as possible if you're just beginning to create your email program but have real intentions of increasing your traffic. You can benefit from the following actions in two distinct ways:

• They'll facilitate the delivery of your present email, and

• They'll let you manage and expand your email volume as it increases considerably more easily.

Specialized IPs

If your company sends a few thousand emails each month, using a shared IP address is OK. However, if you reach the point where you send hundreds of thousands of emails per month, you need to have the appropriate tools in place. In order to safeguard your reputation as you expand, you must own and maintain control over the IP addresses from which you send messages. In our blog post Adding a New IP Address: Is It a Good Idea?, we go into further detail regarding adding (or changing to) a new IP address.

Small-scale traffic segmentation

While segmenting traffic at lesser numbers is not essential, it is still beneficial to maintain the integrity of your transactional and marketing email streams. Compared to marketing newsletters or sales campaigns, transactional emails like receipts, shipment details, and account updates are opened, read, and saved significantly more frequently.

You don't want the reputation and deliverability of your transactional communications to be impacted by the lower engagement of marketing emails. You may increase the likelihood that your transactional and marketing messages will be properly inboxed by sending them from several IP addresses.

High-Tech Segmentation

At lesser volumes, it could be sufficient to only have two IP addresses dedicated to handling your transactional and marketing communications, respectively. But as you reach the millions, just 2 IPs will be insufficient.

Several IPs

You could wish to further separate your marketing or transactional communications for better outcomes, much as marketing emails can affect the reputation and deliverability of transactional emails if they're sent from the same IP.

Suitable Warm Up Procedure

Senders must progressively raise the amount of email they transmit across new IPs after adding them. There are a few distinct reasons why this is done:

Warming up the volume helps you to show that your email is needed by your receivers because mailbox providers are hesitant to deliver a large amount of mail from an unfamiliar IP address.

Beginning gradually offers the sender the opportunity to halt or slow down sending and change their plan before their reputation is seriously harmed.

Hosting of Images and Links

Many email senders find that using link shorteners or image hosting providers makes it simpler to incorporate photos in emails. The problem with this is that other users of the hosting provider may have an adverse effect on your sending reputation. For instance, mailbox providers can consider your photos to be less respectable as well if a bad actor uses the same image hosting site as you, preventing the delivery of your messages.

Achieving High Volume Scaling and Beyond

Sending 5 million emails a month is no easy task, but as you scale to 10 million and more, problems amplify and become more difficult to fix. We like to point out to senders that inbox providers are quick to penalize but slow to pardon.

You don't want issues to arise when you send this much email since they will have a significant negative influence on your company. Fortunately for you, if you've followed the previous stages, you'll have a solid foundation on which to build and may keep reiterating excellent sending habits.
