SMTP2GO contributes towards buying Abel Tasman beach for the people of NZ


At SMTP2GO, we realise that life’s about living. What better way to live life than to enjoy it on a pristine beach in the Abel Tasman National Park.

A few months ago, Duane Major and Adam Gard’ner spotted that the beach was for sale, which meant that someone could potentially snap it up and ban the public from accessing it. They weren’t going to let that happen, so working alongside the Department of Conservation, and with the help of a Givealittle Project, they managed to raise their $2million target and have donated the beach to the people of New Zealand- what an awesome gift!

We’re honoured to be able to say that we were able to contribute our grain of sand towards the project, and donated $500 to the cause.

Faith in humanity restored- “LET’S DREAM BIG, NEW ZEALAND!”

How to avoid my emails appearing in Gmail’s “Promotions” tab instead of the inbox

Newsletter deliverability

Since Gmail changed its inbox layout, many marketers find their emails appearing under the “Promotions” tab in Gmail, instead of the recipient’s inbox. The tabs are optional for Gmail users, but many recipients are choosing to take advantage of them, to make sorting their mail easier.

This isn’t all bad news for marketers, however, as Return Path have done a study of 3 million Gmail users, which shows that emails now have a higher deliverability, read and open rate than before, and less mails are ending up in the spam folder.

If you do want to ensure that your messages end up in the inbox, rather than the promotions tab, you’ll need to speak to your subscribers.

Here are our tips for ensuring that your mails appear in the right place.

  1. Make sure that your mails are completely relevant to your recipients, and that you maintain a high delivery and interaction rate.
  2. Ask your subscribers to add your email address to their address book.
  3. Ask your subscribers to move your emails to their primary inbox.

New SMTP2GO inbound IP addresses

This is a post for current members and will be of interest to you if you have a firewall that is currently only allowing outbound connections to particular IP addresses. In other words, your firewall is restricting all outbound connections except certain IP addresses that you have specified.

To get technical, we are adding new IP addresses to the DNS ‘A record’ for our SMTP service.

Like almost all of our members, if you don’t have a firewall that blocks most outgoing IP addresses, you won’t need to make any adjustments.

The ranges of IP addresses to allow are:

Note: the above ranges are given in CIDR format. If you need the individual IP addresses, you  can convert each range using this website.

We’re making these changes to offer greater reliability in the event of any issues with any one server or location. The changes will be made in the next 48 hours.

Having trouble sending with Outlook on Windows 10?

Since downloading Windows 10, a lot of people have been experiencing issues sending mails via Outlook.

You may see the following error message: User account – Sending’ reported error (0x800CCC13): ‘Cannot connect to the network. Verify your network connection or modem.

If this happens, you’ll need to repair corrupted files by using the Windows System File Checker using the following steps:

  1. Close Outlook.
  2. Right click the Windows Start button and click on Command Prompt (Admin). If this option isn’t available, click Windows PowerShell (Admin) instead.
  3. In the Command Prompt window, type sfc /scannow (note the space in the command) and hit the enter key.
  4. Wait until the process has finished. This shouldn’t take any longer than 20 minutes with a regular hard disk, and much less time if you have a fast SSD drive.
  5. Restart your computer and open Outlook again.

If you continue to experience issues sending, please get in touch!

Having trouble sending with Apple Mail?

Since the OS X Yosemite update to Apple Mail, many clients have been experiencing problems while sending emails. They’ve checked usernames and passwords, swapped port numbers and servers, and re-entered SMTP settings countless times, but nothing seems to work.

Here’s how to fix it:

From the ‘Mail’ menu, go to ‘Preferences’. Once there, click on ‘Accounts’ and then go to ‘Advanced’. There, you’ll see a little checkbox that says “Automatically detect and maintain account settings”. Make sure to untick this box.

Under the ‘Accounts’ heading again, go to ‘Account Information’. Go down to your ‘Outgoing Mail Server (SMTP)’ and from the dropdown menu, choose ‘Edit SMTP Server List’. Find the checkbox that says “Automatically detect and maintain account settings”, and again, untick it. Click ‘OK’.

Don't worry, there's a simple fix...

Go back to your initial settings and check your usernames, passwords, servers and ports. Once you’re happy that they’re correct, close the program and reopen it. Your settings should now stay the way you need them.

8 Things to Avoid with Unsubscribe Links

Some email senders abuse unsubscribe best practices so badly it seems like they’ve gone a step beyond just ignoring the best practices. They appear to almost want to get their messages marked as spam.

To call these bad senders out and to clarify what’s okay and not okay for the rest of us, we’ve put together a list of best practices for email unsubscribe links. If you follow these tips, your messages will get marked as spam less often. You’ll give your subscribers a better experience overall. You might even see your deliverability rates improve.

1) Make the unsubscribe link easy to find.

People scan online far more often than they read. Make your unsubscribe link easy to find for scanners. Here’s how:

– Use type in an easy-to-read typeface, in a size large enough so people don’t have to squint.
– Don’t hide your unsubscribe link in many lines of text, especially long lines of text with no line breaks.
– Don’t grey out the type so the contrast against the white background makes it hard to read. Also, don’t use tiny grey text on a darker grey background.
– Use the word “unsubscribe” for the actual unsubscribe link. Don’t use anchor text like “preferences center” or something nondescript like “site”.

This is what an easy-to-find unsubscribe link looks like:

2) Offer a one-click unsubscribe link.

If people want to get off your email list, that’s fine. Let them go. There’s no benefit to retaining unhappy subscribers. Besides, they may not be unsubscribing because they don’t like your emails. They may be unsubscribing because they simply get too much email.

3) Don’t disable the functionality of your unsubscribe link after a few days.

Some unsubscribe links don’t work after a certain period of time. This results in a terrible user experience, is against our Terms of Service, and in some cases is actually illegal. According to CAN-SPAM, unsubscribe links have to work for at least 30 days after an email list sent.

4) Don’t make people log in to unsubscribe.

Your subscriber is already overwhelmed by his inbox. He probably spends about 28% of his workday just managing email, according to a McKinsey Global Institute report. So don’t make it any harder by forcing him to log into an account he probably doesn’t remember creating before he can unsubscribe.

Definitely don’t give him vague or inaccurate instructions for how to unsubscribe. I ran into this when I tried to unsubscribe from Iberia airlines’ emails. Their email said I should go through these sections on their site to unsubscribe: “Access your Personal Area, My Profile, Subscriptions”. But they don’t actually have sections on their site with those names.

What’s worse, their login process is infuriating. It took me 10 minutes just to get into my account.

5) Make sure your email preferences page shows accurate information.

It’s really frustrating for subscribers to go all the way through logging into an account, only to find inaccurate information about their email preferences. So keep your subscriber database up to date and make sure it works properly.

After logging into the Iberia Airlines website, and finally finding the page with my email preferences on it, I found that according to the preferences I shouldn’t have received their newsletter email in the first place.

The only way for me to stop receiving email newsletters is to change my email address to a fake one in their control panel.

6) Don’t force your subscribers to unsubscribe by replying to your email.

This might have been okay five or ten years ago, but now it’s just bad form. And, as we’ll talk about in a moment, it’s also against SMTP2GO policy.

Another reason this kind of unsubscribe practice is so bad is because after your subscriber has forwarded the email to someone else (or even to a different email address of their own) they won’t be able to unsubscribe through a reply request. This is because they’ll be sending the unsubscribe request from an email address that isn’t on your list – the address they forwarded the email to.

Don't ask people to send you an email in order to unsubscribe

7) Process unsubscribes immediately.

SMTP2GO requires all unsubscribe requests to be processed immediately, as stated in our Terms of Service page, excerpted below:

An opt-out (unsubscribe) link must be placed at the bottom of each email which will allow the recipients to immediately remove themselves from the mail list.

8) Don’t leave out the unsubscribe links.

This is the easiest tip of all to follow. Per CAN-SPAM and CASL, you’re required to have an unsubscribe link in every promotional email you send.

Making unsubscribe links easy to find and easy to use is really not that hard. Just set them up the way you’d want an unsubscribe link to be in the emails you receive.
