You simply must observe some finest practices, and quantity received’t be an issue.
· Get your subscribers’ consent:
It’s simple to fall into temptation, when taking a look at electronic mail advertising outcomes, to purchase an electronic mail listing.

Don’t ship emails to individuals who haven’t requested them.
The perfect method is to make use of clear subscription types and double opt-in (electronic mail affirmation) to make sure every recipient actually desires your content material.
If somebody hasn’t advised you “sure, I wish to obtain your emails,” don’t embody them in your listing; it’s that easy.

Not together with it’s the easiest method for it to be thought-about spam.
That is additionally simple to do, as Mailrelay handles it mechanically for you.

Keep away from generic or suspicious senders like free addresses (Gmail, Yahoo) for bulk campaigns.
As they’re normally blocked.

Anti-spam filters analyze the content material of your emails.
The texts, pictures, hyperlinks, attachments, every little thing.

- Keep away from phrases or phrases that may be thought-about “spam”
- Exaggerated provides (“Generate profits quick!”, “100% free now”)
- Extreme use of $ or € symbols
- Abusive use of capital letters or exclamation marks

It’s higher to extend the restrict little by little, and from there preserve a continuing sending quantity.

In case your contact listing returns many bounces.
Otherwise you maintain making an attempt to ship to these bounces.
That sends a nasty sign to the completely different ESPs.
Similar to for those who obtain many spam complaints, or proceed sending to emails that wished to unsubscribe.
Mailrelay helps you retain your contact listing clear by detecting bounces, managing unsubscribes, and dealing with spam complaints.
