Bulk email and newsletters need another service
Which email you may send through Mailyoto, the sending limits per plan, and what Mailyoto refuses.
Updated 29 October 2026
Mailyoto’s sending limits fit personal and transactional email. Newsletters, campaigns and mailing lists need a service built for bulk sending.
What counts as which#
Ask what made this one email go out.
| kind | it goes out because | examples |
|---|---|---|
| Personal | you are writing to someone | a reply to a customer, a quote, an email to a supplier |
| Transactional | the recipient just did something | an order confirmation, a sign-in code, a receipt |
| Marketing | the business chose to reach a group of people | a newsletter, a sale, product news, cold outreach |
Personal and transactional email is what Mailyoto sending is for. Marketing email belongs with a bulk sending service.
What the rules say#
The abuse page lists these among the grounds for suspending or closing an account, on every plan:
- Spam or bulk email that recipients never asked for.
- Running mailing lists or collecting campaign bounces through aliases.
Every customer shares the same sending servers. One account’s campaign can make mailbox providers refuse email from every customer.
Limits on sending#
| limit | value |
|---|---|
| Emails a month on Pro | 5,000 |
| Emails a month on Max | 15,000 |
| Emails a month on Free | 0 (Free can’t send) |
| Recipients in one message | at most 100 |
Mailyoto counts each recipient, per month from the day your plan renews. The allowance starts again on that day. One day also has a limit, which keeps a large send from using up the month. Replies from your alias count toward the same allowance.
What the sending server refuses#
| case | the response your app shows |
|---|---|
| Month’s allowance used | 550 5.7.0 This account has used this month's sending allowance. |
| One day’s limit reached | 452 4.2.2 This account has no sending left for today. Send again tomorrow. |
| Too many recipients | 452 4.5.3 This message has reached its recipient limit. Send the rest in another message. |
The message scores 4.5 or more as spam | 550 5.7.1 Our spam check scored this message {score} and refused it. |
Where to send bulk email instead#
Use an email marketing or bulk sending service. Add its records to your domain as that service describes. If it needs an SPF include, merge it into your one SPF record: see Merging SPF records.
