Bulk mailing is a practice referencing to the sending of large number of emails to different recipients. It is commonly used by people running an email marketing campaign, it works best for sending regular newsletters and promotion emails. The problem is that some of the most popular email platforms have a limit of how many emails a single address can send in a determined span of time. This can lead to some issues like getting blacklisted.
In other common cases, you can get blacklisted because of the address that you send emails to. As an example, bulk mailing is usually done with help of a mailing list. If the list contains bad addresses or people that are not interested, your emails can produce hard bounces or be reported as spam. This will eventually lad you to be blacklisted.
Below we’ve brought you 6 ways to send bulk email without getting blacklisted. Make god use of the tips presented here and use them to improve your campaign.
One of the main problems people experience with blacklisting is the domain reputation with the ISP. Your internet supplier will use the domain reputation to judge whether you’re worthy of trust. Your reputation depends on the number of spam complaints, bounce rate and spam traps triggered. Aside from this an IP address needs to be prepared or warmed up before doing any bulk mailing.
Preparing the address before bulk mailing will let the ISP know that they’re not dealing with a spammer address. This all can be taken cared for by keeping a good cleaning habit when it comes to your mailing list. Further information on this can be found in our article about why you need to keep a clean list.
Your SPF record will be used by your ISP to determine if an email marketing campaign is legitimate. This is done by comparing the sender’s ID state in the DNS with the IP addresses allowed to email from this particular domain.
While most of the legitimate businesses already have an SPF record set up you might want to check that you have one. This can save you many headaches in the future.
Double opt-ins are a great way to protect your email list from having uninterested subscribers. People that are not aware of why they’re receiving your emails are much more likely to report your mails as spam. This will greatly damage your domain reputation and can lead to being blacklisted.
The double opt-in method is simple and easy to implement for the collecting of subscribers. It basically consists on sending an email with a confirmation link to every new address collected. This allows you to protect your campaign at the expense of a little more effort and maybe a couple bounces.
More information on the double opt-in method can be found in our article about this very subject.
People just may loose interest over time. If that happens you want to make sure to give any subscriber an easy way out. Since the hard way out is usually a spam report, that as we’ve seen can lead you to be blacklisted, this is also in your best interest. Do keep in mind that you’re not really gaining anything from uninterested recipients being in your mailing list. You want to focus all your effort in addresses that can actually lead your email campaign to generate profits.
There are services that can quickly and easily add an unsubscribe link to your email template. In addition to this an unsubscribe link can be set up with relative ease by yourself. Adding an unsubscribe link to your emails also reflects more confidence in your brand and will likely save you a couple spam reports in the future.
The recipients in your list will be more interested on your emails if they know when to expect them. The element of surprise is not a factor that will play for you in this case. People will be less likely to mistakenly report your emails or send them to the trash bin if they know at what time and/or day they arrive at.
In this aspect constancy is key, a good marketing client can help you out with this. Do keep in mind that if they mistakenly report your emails as spam you can be blacklisted. Even if they just never open your emails this shows that they’re not interested and ISP’s notice of this. A key metric to measure this is your open rate, you can find more information on this in our article about good open rates.

Most people have received spam emails at some point of their lives. If you’re in this majority you can take those emails as an example of what not to put in an email.
