Our sent emails get into the spam box in gmail [closed]

Question

I need a help with the following problem I experiencing with gmail.

Any e-mail, whether sent from the website or personal e-mails, that are being sent to a gmail account from our domains get put straight into the receivers spam box

These domains have been used to send mass e-mails from the website.

How can we solve this issue.

thanks

Answer 1

Start by checking if you are on any SBL (spamhaus, abuse.net, spamcop etc), and why, address whatever landed you on the SBLs and contact the SBLs where you are listed and let them know that you have addressed the problems.

Next, check your SMTP server config so it identifies itself properly. Also check the reverse dns name for the IP address(es) used by your smtp server to ensure they match whatever name the smtp server uses.

If the "mass email" you mention is the cause of it (i.e. if you have spammed people) then get new domains, new IPs, and don't send any spam using those.

Answer 2

Setup SPF for your domain, it lets the Gmail and other email providers double-check email sent from your domain is really from your domain and not impersonated by some hacker.

Answer 3

Google have a Bulk Senders Guidelines page that attempts to answer your question.

Answer 4

I'd check the contents of your e-mails.

Are they HTML based?

If so, do they contain a large proportion of links - both web pages and images?

Is your spelling and grammar correct?

The Format section in the link that James Polley provided is relevant here:

• All bulk messages you send must be formatted according to RFC 2822 SMTP standards and, if using HTML, w3.org standards.
• Messages should indicate that they are bulk mail, using the 'Precedence: bulk' header field.
• Attempts to hide the true sender of the message or the true landing page for any web links in the message may result in non-delivery.
• The subject of each message should be relevant to the body's content and not be misleading.

Any or all of these can trigger spam filters.

Another good tool to use for checking blacklist is the blacklist lookup tool at MXToolbox.

The tool will check 100+ blacklists for your sending IP.
