If your VPS server emails aren’t getting through, it’s bad news. Not only does this mean that your customers aren’t receiving their order confirmations and other important information, but it also means you’re losing out on money. A VPS server can be a great way to cut costs, but if people can’t get their orders or other messages from you, there’s little reason for them to keep using your service. Luckily, there are several steps you can take to improve the deliverability of your emails so they don’t get marked as spam by recipients’ mail servers:
1. Avoid Blacklists
Email blacklisting is one of the most common causes of spam complaints. The best way to avoid getting blacklisted is by ensuring that your IP address isn’t listed on any email blacklists. You can do this by checking your IP with a site like MXToolbox or SpamHaus, then making sure you have a good reputation with them before sending any important emails out into the world. If you find that your IP address has been listed, contact the company responsible for maintaining the blacklist and ask them to remove it from their database.
If you still want to send emails through your VPS server but don’t want to risk being blacklisted, there are a few things you can do to protect yourself:
- Use an SMTP service like Sendgrid or Mailgun instead of using PHP smtp functions directly; these services will handle sending messages for you and will check if they’re bouncing back as spam when they go through various servers around the world
2. Send Emails From A Trusted IP Address
- How to check your IP address.
First, you’ll need to know what you’re working with. Your IP address is a unique number that identifies your computer on the internet—think of it like your home address for the internet. You can think about it this way: if someone has an issue with their computer and wants to contact their ISP (Internet Service Provider), they will tell them what their IP addresses are so that they can find out who owns those computers and where they’re located (which helps them fix any problems).
- What’s a trusted IP address?
A trusted IP address is one that has been added by Google or Microsoft as being trustworthy enough not to be marked as spam. If your server emails come from an untrusted source, then there’s no guarantee these emails will end up in the inbox rather than spam folder; however, if you send emails from a trusted source, then Gmail may be more likely to allow them through without marking them as spam!
3. Examine Your Domain And Server
The next step is to examine your domain and server. If you have a dedicated IP address, check that it hasn’t been blocked by either the SORBS (Spamhaus Open Relay Blocking System) or RBL (Realtime Blackhole List). These are lists of servers known to send spam, so if your server is on either of these lists, it means there’s a good chance that email sent from that server will be flagged as spam by recipients.
If you don’t have a dedicated IP address or use shared hosting then you may want to consider contacting the company who hosts your website and ask them about how they handle emails sent from their servers and what steps they take ensure they aren’t blacklisted as spammers themselves
4. Fix Email Authentication Issues
If you’ve followed the previous steps, and your emails are still being marked as spam, it might be time to take a look at how your server is configured. There are three main email authentication protocols: SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication Reporting & Conformance). These protocols allow ISPs to see whether or not an email is legitimate.
Some common problems that arise during this step include:
- Not setting up SPF correctly on the server side
- Not setting up DKIM correctly on the server side
- Having an incorrect default policy for DMARC records in place
To improve the deliverability of your emails, you need to ensure your VPS server emails aren’t marked as spam.
To ensure your emails are delivered to recipients’ inboxes, avoid blacklists.
Blacklisting occurs when an email server blocks a mail server that is on a blacklist. This happens when the receiving server identifies spam attributes in the email header or body. Similarly, if you send from an IP address that is listed on a blacklist associated with distributed networks, your messages may be blocked as well. To avoid this, you should use a dedicated IP address for sending bulk emails instead of sharing it with other users on your shared hosting provider’s servers or VPS servers.
This will help ensure that your VPS server emails aren’t marked as spam by ISPs who have blacklisted those IP addresses due to previous incidents of spamming (spamming is against all major ISP policies).
If you’re serious about your email marketing, it’s important to know how to avoid getting your emails marked as spam. Make sure they’re coming from a trusted IP address, that they’re not being sent too often or too quickly, and that you’ve got everything in place so that your messages can be authenticated correctly by the receiver’s server. If you follow these tips and keep them in mind when setting up your campaigns, then there’s no reason why your emails shouldn’t get through!
