Is BYOIP Proper for Your Electronic mail Program?

What is BYOIP?

BYOIP, which stands for Bring Your Own IP, is a method that allows you to send email through Twilio SendGrid or other third-party email service providers using IP addresses that originally existed on your network.

The advantage of BYOIP is that you can Twilio SendGrid’s scalable email infrastructure when delivering via your IP addresses that have already been set up. Regardless of your email provider, BYOIP presents a number of challenges and requirements. In this article, we’re going to break down the BYOIP process and why it may (or may not) be an ideal solution for your email infrastructure.

The BYOIP process

The BYOIP process is complex (to say the least). It involves updating multiple records and authorizing a variety of parties to ensure your email is delivered as well Reflections of the sendern are not negatively affected.

We’ll go through the process in detail to give you a better understanding of what BYOIP involves and how long it takes. Note that the process described below is not specific to Twilio SendGrid, but rather the steps that all email service providers should take to successfully implement BYOIP.

1. Approval letter: Before porting IP addresses, a Letter of Approval must be set up to identify the IP range being moved from your network to the Twilio SendGrid. This letter is required for both the legal teams of all parties involved and the American Registry for Internet Numbers (ARIN), which manages the distribution of IP resources.

2. Notice: When the ARIN records are updated, the new ARIN owner must use the Border Gateway Protocol (BGP) for. to be announced at least 30 daysso that IPs from major mailbox providers can be pinged randomly. These pings check whether the IP addresses are present, confirm connectivity and identify which network these IPs are currently on.

This step prevents future delivery problems related to Autonomous System Numbers (ASN), which are values ​​that uniquely identify separate networks on the Internet. Some large mailbox providers (e.g. Microsoft) do not allow the delivery of messages from IPs that have not been assigned a static ASN for at least 30 days.

3. RADb records: The Routing Assets Database (RADb) records should be updated to change network provider. The RADb is a public registry of routing details for networks that many Internet Service Providers (ISPs) use to verify the true health of an IP’s current network.

4th DNS and rDNS: You must do all of them before sending Domain Name System (DNS) Updates required to deliver email to your end for any sending domains that you plan to use. This also includes delegating Reverse DNS (rDNS) Zones for the IP space to Twilio SendGrid DNS servers.

5. Twilio SendGrid: At this point, Twilio SendGrid will make the necessary network and DNS changes to enable IP porting, including testing the functionality of the ported IPs.

It takes time to carefully and successfully bring your own IP addresses to an email service provider, requires significant paperwork and consideration of best practices. Until unforeseen problems internal or third party, the timeline from start to finish Implementation of BYOIP with every email service provider is at least 3 to 4 months. This estimate includes downtime for the IPs and hard switchovers. If the IPs are completely warmed up, this time can be reduced to a few weeks for logistics and a few hours for the transmission of the IPs to our network.

BYOIP considerations

As you can see from the overview above, BYOIP is not the “quick solution” for brand new IPs. Although there are certain use cases for BYOIP, the consideration of time should be taken into account.

Length of time

It boils down to that BYOIP is not an alternative to IP warm-up phase. With a 3-4 month process, BYOIP implementation will likely take longer than warming up an IP. And once BYOIP is complete, it is recommended to slowly warm up these IPs on the recipient servers as they were in a dormant cooldown state.

At the same time, you could Sign up for a Twilio SendGrid email account and warm up dedicated IP (s) to a daily email volume of over 500 million.

BYOIP use cases

Migration from an on-premises email infrastructure

BYOIP isn’t for the average sender and doesn’t provide a shortcut to IP warm-up, but it is useful when you are Migration from an on-premises email infrastructure to a cloud-based solution like Twilio SendGrid.

If you are migrating from a variety of IPs that you own and deliver from, you may already have built enough reputations with the recipient servers to make it beneficial to port IPs to ours Infrastructure for further scaling. This process can be carried out for the logistics in a time frame of 2 weeks and the transfer can be carried out in a few hours.

Sending on behalf of many

BYOIP can be useful if you are shipping on behalf of many customers. If you have a large user base that you broadcast on behalf of, you may have many users setting up allow lists with their recipients that contain your personal IP ranges. BYOIP would reduce the friction your users had when migrating these allow lists at the expense of potential downtime. (It’s worth noting that IP Allow Lists are mainly used in internal or business-to-business (B2B) shipping.)

Regardless of whether you bring your own IPs or not, Switching to Twilio SendGrid would still require a DNS update for anyone looking to send email using their domain. Consider this a necessary step for either migration solution.

No matter which way you lean We recommend working with our Expert services and customer success teams with years of experience making this type of migration successful.

Takeaways

Use of BYOIP as an alternative to IP warm-up will land you in hot water.

There will likely be some downtime during which these IPs will not deliver email consistently. During this time, the reputation of your IP addresses falls outside the recipient’s server algorithms.

Alternatively, senders with a high volume can also be ramped up and messages in full within 14-30 days. to deliver Twilio SendGrid’s dedicated IPs. There are other ways to avoid downtime entirely. For example, both email sending and email environments can slowly migrate from your previous solution to Twilio SendGrid to warm up dedicated IPs from Twilio SendGrid.

Starting over is the perfect time to strategically plan deliverability.

Our Expert Services team has worked with hundreds of enterprise customers to develop a unique architecture for each use case that can optimize the deliverability of Twilio SendGrid’s IPs. Deliverability is a balance of many variables, and the reputation and history of IPs outside of our normal network is an unknown that can be avoided. Introducing a well thought-out IP warm-up process and developing the appropriate IP segmentation are key to building a healthy email infrastructure that can be easily achieved without BYOIP.

Some senders may be eligible for BYOIP, but it’s important to know the pros and cons and understand the process.

If you are a high volume sender using an on-site email infrastructure, BYOIP can help you maintain the reputation you have built for yourself with recipient servers. If you are sending on behalf of many customers sending B2B traffic that requires allow lists, BYOIP eliminates the need to update allow lists because IPs are not changed during migration. Regardless, you should weigh these pros and cons, including required downtime and possible rewarming after IPs have cooled down during downtime.
