InboxAlly
InboxAlly
We engage with your emails to teach inbox providers not to send your emails to spam. Our clients have seen their open rates more than DOUBLE within 1-2 weeks! Highly engaged recipients not only open emails, but scroll down as they read. So long as the content is longer than the page, this should be done for nearly all opened emails. When a recipient goes out of their way to take an email out of spam, they are telling the inbox provider, hey, you made a mistake. Moving an email from the promotions folder to the primary inbox tells inbox providers that you disagree with their sorting criteria and it and similar emails should go to the primary inbox. Demonstrates that recipient is interested in the content of your email. We have a set of random generic replies we use for this. Marking an email as important can essentially be interpreted by the inbox provider as "This email is extremely valuable, never send it to spam." -

Sendio
Sendio’s Opt-Inbox is a proprietary sender management process, acting on messages having cleared email security, which would otherwise be released into a user’s inbox, ensuring that recipients only receive messages from desirable sources, whether from individuals or subscriptions, leaving the new yet undecided sources to the recipient’s discretion in a queue separate from the usually messy quarantine queue. Despite being protected by advanced email security systems, many inboxes continue to be inundated with countless security-cleared messages comprised of persistent sales pitches and marketing communications, distribution lists and bulk sources. Separating harmful messages in the quarantine queue from nuisance and potentially desired ones is increasingly difficult. This can become particularly troublesome for executives and professionals who can’t afford to overlook an important email and find out later they had a desirable message (false positive) in their cluttered quarantine queue.Starting Price: $795 per year -

Emelia
Your cold emailing is better than ever! With an intuitive platform, detailed analytics and exclusive features. Writing an effective cold email is a crucial step in email prospecting. Also known as cold mailing, it's a prospecting technique that fits into a company's business strategy and aims to generate new leads. Writing a cold email is a unique exercise. You can't write to 10,000 people in the same way. You're likely to fail. This is where personalization comes in. The more personalized your email, the less your recipients will feel spammed. Your name and email address should be professional and consistent with your brand or company. Recipients are more likely to open an email from a credible source. Your email's subject line should be attention-grabbing and encourage recipients to open it. It should be short, clear, and give an overview of the email's content. Consider using relevant keywords and personalizing the subject line for each recipient.Starting Price: $20 per month -
