Utilizing email for event invitations is a common and effective method to inform potential attendees. However, there are various challenges in ensuring the success of this approach. These challenges include overcoming spam filters, capturing the recipient's interest to open and read the email, and, most crucially, motivating them to take the desired action - registering for the conference.

While the conference itself must be relevant and engaging, with participants and speakers that align with the interests of the target audience, attention to technical details is equally vital to ensure your message reaches its intended destination.

Here are some recommendations for crafting and sending conference invitations:

Effective Email Subject

Keep it concise around 70-80 characters, so recipients swiftly understand the conference's essence and why it's relevant to them. A compelling subject ensures your email isn't overlooked or deleted.

Sender's Name and Address

Avoid using a generic sender, like a frequent newsletter distributor or publicist, as it diminishes the chance of your email standing out amidst recipients' inboxes. Instead, utilize your organization's email and domain for credibility. Emails from a reliable source tied to the conference's theme are more likely to be opened and acknowledged.


The first sentence is displayed as a PREVIEW of the email and may also affect its opening. Try to avoid sentences that indicate that the email is widely distributed - such as "dear customers. A sentence that includes the invitee's name, such as "Hello Daniela", helps convey the message that this is an email sent personally to the recipient, and as such, it is more likely that it is indeed relevant to him.

Compelling Email Content

Optimizing Email Structure

Given the influx of emails people receive daily, it's crucial to recognize that recipients often scan rather than read line by line. Avoid lengthy paragraphs, and opt for concise, relevant information. Additionally, ensure images are of a reasonable width (max 500 pixels) for easy viewing without the need for scrolling, facilitating a seamless scanning experience for your audience.

Recipient Management Guidelines

When sending emails, ensure relevance by targeting individuals who genuinely find the content valuable. Avoid redundancy by refraining from sending duplicate emails to the same recipient. Grant recipients the ability to opt out, allowing them to effortlessly remove themselves from your mailing list if they wish.

Optimal Delivery Timing for Conference Emails

For professional conferences, consider sending emails during midweek, particularly in the hours following the morning until 2:00 p.m. This timeframe allows recipients to engage with their emails when they are more likely to be attentive. Sending emails right after the weekend may lead to your message getting lost among the influx of emails that accumulate during this time. Additionally, on Thursday afternoons and holiday evenings, individuals tend to focus on urgent tasks or weekend plans, diminishing the attention your email may receive.

It's essential to avoid timeframes when individuals are less likely to take immediate action, such as registering for the conference. Post-weekend, there's a risk of your message being forgotten. Choose a strategic timing that aligns with when your audience is most receptive and likely to act on the information presented.

Preventing Spam Classification

To avoid being flagged as spam, implement essential protocols for mail server verification, such as DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF).
