Best Practices - Sending from Premium Email

Person-to-Person

The following best practices are generally considered sound advice for any person-to-person email correspondence and are not necessarily specific to our service. These tips and guidelines are intended to reduce the possibility of your email ending up in your recipient’s spam folder, or worse, rejected by their email provider. The goal is to help you avoid the well-known mistakes that commonly trigger spam filtering in most modern email services and clients.


Content

  • Use a reputable and well-known email client. This will ensure that the email you send will be properly constructed and communicated.

  • Things like providing HTML and text versions of the message content, properly constructed and formatted email headers, and adherence to specifications for sending email (SMTP) are fundamental to sending good mail.

  • Keep your message’s layout as simple as possible. Avoid complex formatting.

  • If you’re sending HTML email, ensure that it’s properly constructed. Things like missing/empty tags, poor formatting, and non-standard conventions are spam indicators.

  • Don’t insert active components (javascript, ActiveX, plug-ins) in your message. If you need rich media content, just link to a media-rich page on your web site.

  • Use personalized greetings/salutations. Generic salutations make your content more likely to appear as unsolicited mail to spam filters.

  • Do not use links that contain IP addresses. Using IP addresses is a huge red flag for spam filters.

  • If you link to other companies’ sites in your message content, ensure that they are reputable sites.

  • Be careful about using shortened urls in your message content. Shortened links are often used by spammers to mask the destination of the link; spam filters often flag messages with shortened links as spam.

  • Avoid using symbols for letters in words; spellings like “[email protected]”, “|etters”, and “g00gle” in your emails are often classified as spam.

  • Do not overtly reference topics that are highly recognized as spam such as Rolex watches, medications, prescription drugs, or financial institutions.


Subject Line

Pay attention to your subject line. Avoid the following:

  • Punctuation (especially exclamations and question marks).

  • Using only capital letters.

  • Words such as “urgent”, “free”, “guaranteed.”

  • Text with spaces between every letter, such as “H e l l o.”


Attachments

  • It is becoming preferable to avoid attaching files to your messages. Most cloud file sites now offer shareable links you can provide in your email (Box.com, Microsoft OneDrive, Google Docs, etc.). Since attachments are a common way of distributing viruses (especially for Windows users), filters are becoming more strict on attachments. Zip file attachments are a common example of this.

  • If you do send attachments, be sure they are named correctly and the spelling is correct. Also, choose a name that is simple and specific to the nature of the attachment.

Person-to-Many

If you need to send email to a larger number of recipients that falls within our sending limits, then here are some recommendations to ensure delivery both on our system and at other providers:

  • Follow all the person-to-person best practices for creating the your messages.

  • Ensure all recipients are end-user destinations.
    • Our platform is intended for person-to-person communications.

    • Ideally, these are people you already correspond with person-to-person.

  • Use DNS-based sender authentication records for your domains (SPF/DKIM/DMARC):
    • The more email you send, the more important it is that receivers can authenticate your email is from an authorized source.

  • Avoid 'blasting' emails to many people.
    • Tools like mail merge can allow for many messages to be generated/sent in a short period of time.


Bulk Email

  • Our hosted email platform does not offer bulk email services. We recommend using a reputable bulk email service to send out your content. This will ensure your emails are sent out safely and conform to industry best practices for delivering high-volume email. These services include features like email list hygiene, recipient opt-in and unsubscribe management, and content verification to ensure your message does not match typical spammy patterns.

  • Below is some helpful information for managing your bulk email needs.


Sending

  • We do not offer bulk email services. We recommend you use a reputable bulk email service to send out your content. This will ensure your emails are sent out safely and you do not end up getting blocked. Reputable mailing companies provide software and services to ensure your bulk email is delivered in a manner that mail providers will accept as good mail.

  • If you are sending emails to a large number of recipients using our email, please be sure to respect our mail requirements.

  • Follow all the person-to-person best practices for creating the content for your message.


Email Lists

  • Ensure your recipient lists are current and accurate.

  • Do not use paid-for lists.

  • Sending emails to large numbers of invalid recipients is a clear indicator of spam. Also, mail providers and ISPs can use common invalid addresses as spam traps. Sending mail to these spam traps can result in your domain being blacklisted.


Opt In

  • Ensure that you’re only sending mail to users who specifically requested it.

  • Use confirmed opt-in practices when collecting email addresses for mailing lists to reduce the chances of your messages being considered unsolicited. Unsolicited email is more likely to be marked as spam by recipients, leading to you being flagged as a spammer by content filters.


Unsubscribe

  • Make sure that if you send email newsletters or communications to your customers, always provide them with a means to remove themselves from your mailing list.

  • Maintain a safe and reputable business website. It should include easy access to any privacy policies and contact information for your business.


Content

  • Be sure that other companies you allow to include references to your business are reputable. If they send out spam and your company information is referenced in those emails, your domain could be flagged as being related to spam.

  • Conversely, be careful which domains/companies you reference in your emails. If those companies are already flagged for spamming activities, your email could be marked as spam or blacklisted for referencing those domains/companies.


Authentication

  • Authenticate with Domain Keys Identified Mail (DKIM) – This will provide you with a consistent reputation across your domain, regardless of what IPs you send mail from. Read more at http://www.dkim.org/.

  • Publish an SPF record – This will tell us which hosts can send messages from your domain. More information is available at http://www.openspf.org/.

  • Publish a DMARC record – Messages spoofing your domain will appear unauthenticated and therefore be rejected, depending upon your policy disposition. You can learn more at https://dmarc.org/.
