There are numerous questions and points to bear in mind when it comes to mass emails. You can do more than just send simple newsletters – you can reach large groups of recipients efficiently, reliably and professionally. This can be achieved with a whitelisting-capable provider or an SMTP relay, which makes sending emails professional and scalable.

We have summarised five key aspects of bulk email sending for you.

We are frequently asked questions on this topic. That is why we have compiled the most important points for you and highlight five key questions here:

How can I reach large recipient groups reliably and securely?
By using a whitelist-enabled provider or an SMTP relay, you ensure that your emails do not end up in the spam folder and that your sender reputation remains protected.

How many emails can I send per hour or per day?
The sending rate depends on the provider, your tariff and the infrastructure. Many providers allow thousands to tens of thousands of emails per hour, particularly if the account is set up to handle high volumes.

Do I need a dedicated tool for this, or is an SMTP relay sufficient?
For many use cases, an SMTP relay is sufficient to send emails automatically and at scale from your existing infrastructure – without the need for a comprehensive email tool.

How can I measure the success of my emails?
Open and click-through rates can also be tracked via a relay if you integrate the appropriate tracking mechanisms. This allows you to quickly identify which content is well received.

How can I optimise my deliverability?
Ensure you have authentication in place (SPF, DKIM, DMARC), clean lists and regular maintenance of your recipient addresses. A provider that supports whitelisting will also help you ensure a high delivery rate.

Centralised recording in the CRM system gives companies a standardised approach to tracking initial contacts and leads. Data is recorded in real time, enabling your team to obtain accurate information about previous touchpoints and interactions.

When you send emails, they do not simply travel through the network like a letter.

Instead, computer programmes use so-called protocols – agreed-upon rules – to ensure the message is transmitted correctly. The most widely used protocol for sending emails is SMTP, short for Simple Mail Transfer Protocol.

SMTP specifies how emails are sent from your email programme or server to the recipient’s email server. It defines the commands, formats and procedures so that both sides – the sender and the recipient’s server – understand exactly what needs to be done

For simple email campaigns, your own server or provider usually handles the sending. However, as soon as you wish to send large volumes of emails – such as member information, newsletters, notifications or marketing campaigns – sending via your own server can become problematic due to the volume of emails.

This is where the SMTP relay comes in. A relay is an intermediary server that forwards and delivers your emails. The relay takes on the task of transporting messages efficiently and reliably to their destination addresses without overloading your own server.

A key advantage of an SMTP relay is improved deliverability.

Many relays use so-called whitelists and have a good sender reputation, meaning your emails are less likely to end up in the spam folder. Furthermore, relay servers can send large volumes simultaneously and allow you to scale your mailings, for example if you wish to reach thousands of subscribers.

In summary: SMTP is the protocol that governs sending, whilst a relay is a specialised server that reliably forwards emails. Together, they enable secure, efficient and scalable delivery – from individual messages to large-scale email campaigns.

Important: Please make sure you update and configure the DNS settings for your mailing domain accordingly.

Sending bulk emails via a professional email marketing tool offers businesses numerous advantages. With such a tool, you can reach large groups of recipients simultaneously without overloading your own email server.

Emails are delivered reliably, personalised and designed to be visually appealing.

Emails sent using a mailing tool can be customised to a high degree – whether using a template or not. Include photos, your logo, maps and much more to give your emails the personal touch that matches your corporate identity.

An email marketing tool enables you to easily plan, segment and automatically send content. You can target different audiences, include personalised subject lines and content, and measure responses such as opens and clicks.

This allows you to identify exactly which content resonates particularly well with your recipients and enables you to continuously optimise your strategy.
Particularly handy: many tools automatically handle deliverability, whitelisting and unsubscriptions, ensuring your messages reliably reach your recipients’ inboxes. At the same time, you save time and effort, as recurring campaigns can easily be automated.

With an email marketing tool, you can turn the sending of large volumes of emails into an efficient, secure and traceable process – whether you’re sending newsletters, notifications or promotional emails.

Here, too, it is important to configure the DNS records for your sending domain accordingly.
