For companies that need to send frequent marketing and transactional emails to their audiences, it can be a challenge to find the right email service provider. Email marketing is about more than sending out customized campaigns and tracking analytics—it’s also about ensuring reliability and deliverability.
Many of the most common service providers, including gmail.com, limit the number of emails that can be sent simultaneously, and up to 20% of legitimate messages from commercial senders end up in spam folders.
While it can help to embrace best practices, such as double-opt in permissions, frequent list-scrubbing, and appropriate email authentications, it can become more difficult to follow proper list management protocol as your recipient list scales to the thousands, or even the millions.
You may quickly find that your list is corrupted by spam bots, and that your campaigns are falling flat due to poor open rates, bounced messages, and delivery to spam folders. In some cases, you may even see your IP address blacklisted and throttled by certain email service providers as your sender reputation score declines with each bulk mail.
If you’re focused on high-volume email marketing, your company needs an email service provider that’s able to provide the technology and support team to optimize your email deliverability and enhance your sender reputation.
