Disable sender confirmation in Mailrelay v3

Noé Soriano

Perhaps we should start by explaining what the reason might be for disabling sender confirmation. This system is implemented to guarantee the security of the system and prevent sending with poorly configured senders or from domains that are not authorized by their legitimate owners. So, what could be the reason for disabling it? Well, it’s […]

Mailrelay now supports AMP for Email (Accelerated Mobile Pages)

Noé Soriano

AMP stands for Accelerated Mobile Pages, a project developed by Google and other partner companies to improve how fast websites load on mobile devices. It matters for email marketing because it has specific sections for adding this code to emails, giving them very interesting features and adding a lot of value to campaigns and newsletters […]

Failed accounts in the email database: the importance of removing them

Noé Soriano

Many customers are surprised when they have deliverability problems in B2C after being very careful to comply with data protection legislation: they have collected their subscribers unambiguously, those subscribers want to receive the newsletters, and unsubscribes are processed promptly. Unfortunately, sometimes they have overlooked a very important detail: removing from their database the ISP accounts […]

SMTP relay server and smarthost: what they are, how they work and when to use them

Noé Soriano

An SMTP relay server, also called a smarthost, is an intermediary SMTP server that receives email from a company, application or local server and forwards it to the recipients’ servers. Its function is to centralize and manage outgoing email in order to simplify the infrastructure, apply security controls and improve deliverability. Mailrelay can be used […]

What is SpamScore? And did you know that with Mailrelay you start at -6.2?

Noé Soriano

SpamScore is a scoring system that measures the potential risk of an email to try to determine whether or not it is spam. Every anti-spam system uses this score: the filter adds or subtracts points based on different rules and, if the total reaches the threshold set in the system, it treats the message as […]

Segmenting subscriber lists by chosen sending frequency: weekly and monthly

Noé Soriano

We’ve barely covered this topic on our blog until now, yet it’s a very important type of segmentation for keeping subscribers loyal, perhaps the most important of all. When we talk about segmenting by sending frequency, we mean how often our subscribers want to receive our communications (our bulk mailings). This segmentation won’t necessarily improve […]

I have unsubscribes in my dashboard but I don’t use the Mailrelay link. How is that possible?

Noé Soriano

First of all, note that mailings must always include a clearly visible, hassle-free unsubscribe link to comply with Spanish and international anti-spam regulations. However, even if you don’t use Mailrelay’s dynamic unsubscribe links (because you use your own on your portal, for example), unsubscribes may still appear in your dashboard, in the corresponding section under […]

You are not receiving emails on your own corporate domain

Noé Soriano

This is a very common problem that many users report to us. It happens because many mail servers and anti-spam systems let you set up a rule so that any email arriving from the corporate domain is rejected if the sender’s IP is not that of the organization’s mail server or servers. It is similar […]

Email Bounce Reasons and Possible Solutions

Noé Soriano

This time we want to approach the topic from a perspective closer to marketing and sales teams. In more down-to-earth language, we’ll go through the reasons behind each bounce and, perhaps more importantly, what we can do (if anything can be done, which isn’t always possible) to rescue that subscriber from their failed bounced status […]
