In the previous installment of this series we discussed the components that are needed to run a self-hosted email marketing platform. In this article we will go over some of the criteria to consider when researching a provider to self-host an email marketing automation software and explore some possible providers.
Types of Hosting
The providers’ hosting options will usually fall into three major categories. They are shared hosting, bare metal/dedicated servers, and Virtual Private Servers (VPS).
In the case of Interspire Email Marketer, using a shared service hosting package will usually not work for a number of reasons such as the resources made available may be severely restricted, the underlying shared software may not meet the system requirements, or may simply violate the Terms of Service of a shared hosting plan.
On the other hand, unless one is running a relatively large email marketing operation, the costs of a dedicated bare metal server may not be justified to host the typical instance of Interspire Email Marketer.
Virtual Private Servers (VPS ) are designed to provide a balance between flexibility, performance, features, and pricing. Virtual servers are usually provisioned on shared hardware and, by using modern virtualization techniques, give the illusion of a dedicated server. This results in an environment providing similar flexibility, control, and performance levels to a bare metal server while doing so at a significantly lower price point than that of a physical server.
Factors when choosing a VPS Provider
There are many VPS providers to choose from. Here are some of the factors to consider when choosing one to host your email marketing automation solution.
Can you send mail?
The first question to ask is whether the provider allows direct sending of email from the VPS, in other words is port 25 open? If you are using a dedicated sender as recommended then this is not an issue. However, if you are planning on sending mail directly, it goes without question that one must choose a provider that allows mail to be sent.
Most providers will disable port 25 by default to prevent spam from being sent from their servers. Some will open port 25 if requested, while others will not open it under any circumstances. By the nature of how reputation is built over time, there is the possibility that the providers that have port 25 may have IP addresses that have low reputation or may even potentially be black listed.
Clean IP Addresses
As hinted in the previous paragraph, the reputation of the IP address assigned to your VPS is one of the key factors in determining if your emails will be delivered to your recipients. Once again, this is a factor if you are not using a specialized email service provider. The addresses assigned to your VPS will most likely have been previously used on another VPS. You should check the reputation of the IP address before moving forward.
Reverse DNS Configuration
A number of specific DNS records are essential to email sending as they provide various methods for the recipients’ systems to authenticate the sender of your emails, the emails themselves, and letting the recipients know that the emails are really coming from you.
One of those types of records are reverse DNS (rDNS) or Pointer (PTR) records. As the name implies, those records will map IP addresses back to names. Unlike other records such as SPF, DKIM and DMARC that are set with your DNS provider -which may or may not be the same as your hosting provider- PTR records are almost always set at/by the service provider. They should allow you to easily configure the reverse DNS Record for the IP address(es) assigned to your server, and ideally allow you to do so without an additional fee.
As your newsletters, email marketing efforts, and other business activities are more and more successful, the capacity of your VPS should be able to grow with your success. Your provider should enable you to easily increase the resources allocated to your VPS over time without too many complications.
The ability to make backups and, more importantly, to easily restore is important to protect this critical pillar of your business. The backup options should be flexible and meet the preservation requirements of your business to continue to serve the needs of your customers.
Graphical User Interface (GUI)
The providers usually provide intuitive and easy to use graphical user interface to provision and configure the VPS you will be using. Activities such as setting up rDNS, backups, additional IP addresses as needed, possibly firewalls should be easily accessible and executed from within the environment supplied by the provider.
Although the installation of Interspire Email Marketer is relatively simple and its day-to-day maintenance requirements minimal, there will be times when contacting your provider’s customer support will be necessary. Depending on your team’s technical knowledge and the type of VPS service subscribed to, say between a managed or an un-managed service, the method and convenience of access to the customer support desk can be a factor. The providers may offer email, chat, phone-based, or a combination of the three to provide customer support. Choose one that will match your needs and expectations.
The physical location of a server’s datacenter may have an impact as well. The impact can be both from the legal perspective and on how well the instance performs.
Depending on the jurisdiction that you operate from, it may be necessary to host your server in a jurisdiction that is compatible with the legal environment in which you are operating. (This is not legal advice; please consult a lawyer). For example, with the current state of the safe harbor agreements (or rather, lack thereof at the time of this writing) between the US and the European Union, it may be necessary to host your data on a European hosted server to help comply with GDPR’s requirements.
From a performance perspective, it would not be ideal to host your services at a location requiring intercontinental transmissions say if your customers are primarily in Australia.
With a VPS provider having strong security measures, you can better safeguard your data, mitigate hacking, DDoS attacks, and other nefarious activities. If you are using a managed VPS service, they will also keep your VPS updated and patched as necessary.
Most providers will offer free DDoS protection and SSL certificates. In addition to these, look for packages that allow for regular automatic backups as mentioned before, perform malware scanning, and offers firewall protection.
You will have a wide range of operating system choices from VPS providers. Most hosting providers will offer a menu of Linux and Windows options, and you would need to check the compatibility of the option chosen against the server requirements of your self-hosted email marketing software. For example, although Interspire Email Marketer will run on Windows with a XAMP stack, the official requirements call for a Linux variant.
Lastly, the pricing structure of the hosting packages is also a factor. Beyond the obvious that the price should meet your budget, you should look at the resources being offered in each of the pricing options presented by the hosting provider, and see that they are commensurate with the resources and other intangible services, such as customer support, that you are getting access to.
In addition, a provider that offers some form of trial, money-back guarantee, or no long-term contract commitment may ease your selection.
