High reputation is key to getting your emails delivered to recipients' inboxes. That is why we meticulously maintain high reputation of our IP addresses and employ SPF, DKIM, and DomainKeys authentications protocols to ensure the deliverability of your emails.
Sending speed is crucial for a timely delivery, especially for businesses with massive subscriber lists. We operate powerful hardware to make sure that your newsletters are delivered in the shortest time possible.
SENDER integrates feedback loop system with major email service providers, such as Outlook/Hotmail, Yahoo, AOL and others. This allows us to get instant notifications when someone marks your email as spam and take corrective actions.
When you send a campaign, our platform analyzes all rejected and returned emails. We will automatically disable non-existing email addresses to keep your list clean and up to date.
Dedicated IP addresses provide you with total control of your email reputation. We recommend them if you send over 500 000 emails per month.
