You're using the Emailing feature and notice that your sending frequency is limited. This limit depends on several factors, including the impact your sends have on reputation.
Below you'll find the best practices we've put in place, and how to increase your sending frequency.
Understanding reputation
Definition
When you send email campaigns, email providers (Gmail, Outlook, Yahoo…) factor in the sender's reputation to determine whether emails are spam or not.
Reputation is the trust score tied to the sending server, and it is shared across all our customers. We send your first campaigns in batches to detect any sends that could negatively affect it.
If you send unsolicited emails, send to addresses that no longer exist, or receive a high number of spam complaints, your sends can damage the shared reputation and ultimately get blocked.
What poor reputation means for your sends
A poor reputation hurts your email campaigns' deliverability rate — and rebuilding credibility with email providers is an uphill battle. It determines whether emails are:
- Delivered to the recipient's inbox
- Sent to the recipient's spam folder
- Blocked entirely
Some email providers use aggressive spam filters that block delivery altogether. We have no control over this filtering, but there are steps you can take to work around it.
Because this reputation is fragile and shared by all platform users, we have put control measures in place.
What we do to protect reputation
Throttled initial sends
As a new customer, your access to the emailing tool starts throttled: your initial sending frequency will be low, and will increase over time.
Your email campaigns are sent in batches of 50 at first, with that quota doubling every 30 minutes.
This approach lets us verify that your spam/bounce rate is low — once confirmed, your sending frequency will increase.
Managing bounces and spam
We have a dedicated article covering how to manage addresses flagged as bounced or spam.
An unsubscribe system
When you send an email campaign through Springly, recipients can unsubscribe at any time.
This option appears at the bottom of every email sent, like this:
When a recipient clicks the "I no longer wish to receive these emails" link, they will be unsubscribed from all mailing lists.
This unsubscribe system is a best practice: it gives recipients an easy way to stop receiving your emails — reducing the likelihood that they'll mark you as spam instead.
Increasing your sending frequency
Beyond the measures we put in place, you can improve your chances of increasing your sending frequency by following a few best practices.
Improve your email content
The more engaging your email, the more likely people are to open it. Reputation is influenced by recipient behavior — particularly open rates and spam complaints.
Sending the right content to the right audience is one of the best ways to keep spam rates down. A few tips:
- Only send your highest-value content
- Track contact interest and engagement using send reports.
- Segment your contacts by creating multiple mailing lists.
Other factors can trigger email providers' spam filters:
- Using special characters (such as #!$À) in the email subject line.
- An excessive proportion of images. If that's the case, favor text-based content instead.
- Redirect links pointing to a domain with a poor reputation.
Only send emails people asked for
The stronger your relationship with recipients, the less likely they are to mark your emails as spam.
Ask your contacts whether they'd like to receive your newsletter rather than signing them up without consent. At the same time, ask them to confirm or update their email address to make sure that:
- the address still exists — otherwise your email risks a hard bounce or soft bounce,
- the address is still actively used — otherwise your email may never be read.
Purchasing a contact database should be avoided at all costs.
How sending frequency increases
As explained above, your initial sends are split into batches distributed according to an hourly quota.
Frequency increases are tied to your spam/bounce rate: at set intervals, we review accounts that have reached their quota within the past 30 minutes. If their rate is low, we double the quota — and so on.
You need a combination of high send volume and a low spam/bounce rate to increase your frequency. The increase will take effect on your next campaign.
If your campaigns show a high rate, we will temporarily block your sends to carry out a review. This also allows us to permanently block any campaign that severely damages reputation and would have triggered repeated blocks regardless.
