Send personalized emails

If you want less spamming and a better open rate, try personalizing your email by using the client's first name in the emails like “Hi, Edward”.

Segment your email list

Characterize your email list based on certain criteria like location, industry, behaviour, and so on. This will help to tailor your emails and improve their efficiency.

Implement email authentication measures

  • Neglecting personalisation: While sending mass emails make sure you’re not sending generic content and tone to your contacts. This will drop the engagement rates and lead to spamming complaints. Try adding the client's name in the greeting or tailoring the content specifically to the industry or user behavior to ensure a personalised touch.
  • Lack of segmentation: If you’re sending the same email to your whole contact list, it will sound like an automated email and damage your account's reputation. Make sure to segment your contact list based on some criteria like location, industry, buying intent, etc to make sure you target the desired audience rightly.
  • Overlooking the subject line: The subject line will be the first impression of your whole email. If it is catchy or attention-grabbing, the client will be instantly compelled to open and check what’s inside. Otherwise, they will consider it another sales email they don’t want to open.
  • Ignoring Mobile optimisation: Most people nowadays prefer opening an email using their mobile phone. Make sure your email is mobile-friendly and it appears easy-to-read across all devices. To ensure this send a test email to yourself and check it on your phone to know how it appears.
  • Sending without testing: Even your final email can have issues like formatting or invalid links. To ensure that the email sent is perfect, send yourself a test email and check everything within it before sending it to your contacts.
  • Non-compliance with anti-spam laws: Make sure you comply with data protection and privacy laws like GDPR if you’re sending mass emails. Non-compliance can lead to complaints from the client side and permanent suspension of your email account.
  • Overboard with images and large files: Make sure you’re not adding larger files or too many media options if you’re adding media to your email, as this can trigger the spam filters and land your email in spam folders.
  • Inconsistent sending schedule: Ensure you have selected a specific time while sending mass emails, either daily, weekly or monthly to send your emails. The inconsistent timing will annoy the recipient leading to a negative action taken.
  • Neglecting analytics: Make sure you are checking the results and analytics when you start sending mass emails to determine whether your campaign is doing well or if it would be better to bring some changes in it, try using the A/B testing method to check analytics to ensure which method is doing well. 
  • Using a no-reply sender address: A no reply-sender address sounds automated and can annoy the person receiving the email, make sure your sender address email is more friendly.
  • Forgetting to include a clear call to action(CTA): Without a clear CTA mentioned in your email, the recipient will be left confused about the next steps, especially if they are interested in moving forward with your email intent.
